TD APC Change. 20180217

Changed the build timer for APCs from 14 seconds to 15 seconds.

An oddity here is that it wasn't exactly on 14 seconds. It was closer to 13.6 seconds.
Changing this to be about 14.8 seconds will help a little from the mass production problem
rather then changing damages or HP further.

-* [.NET Framework 4.6.1 (Developer Pack)](https://dotnet.microsoft.com/download/dotnet-framework/net461) (or via Visual Studio 2017)

+* [liblua 5.1](http://luabinaries.sourceforge.net/download.html) (included)
 
-Type `make dependencies` in a command terminal to download pre-compiled native libraries for:
-* [SDL 2](http://www.libsdl.org/download-2.0.php)
-* [FreeType](http://gnuwin32.sourceforge.net/packages/freetype.htm)
-* [zlib](http://gnuwin32.sourceforge.net/packages/zlib.htm)
-* [OpenAL](http://kcat.strangesoft.net/openal.html)
-* [liblua 5.1](http://luabinaries.sourceforge.net/download.html)
+You need to fetch the thirdparty dependencies and place them at the appropriate places by typing `make dependencies` in a command terminal.
 
 To compile OpenRA, open the `OpenRA.sln` solution in the main folder, build it from the command-line with MSBuild or use the Makefile analogue command `make all` scripted in PowerShell syntax.
 
-Run the game with `launch-game.cmd`. It can be handed arguments that specify the exact mod one wishes to run, for example, run `launch-game.cmd Game.Mod=ra` to launch Red Alert, `launch-game.cmd Game.Mod=cnc` to start Tiberian dawn or `launch-game.cmd Game.Mod=d2k` to launch Dune 2000.
+Run the game with `OpenRA.Game.exe Game.Mod=ra` for Red Alert or `OpenRA.Game.exe Game.Mod=cnc` for Tiberian Dawn.
 
 Linux
 =====
 
-Mono, version 5.4 or later, is required to compile OpenRA. You can add the [upstream mono repository](https://www.mono-project.com/download/stable/#download-lin) for your distro to obtain the latest version if your system packages are not sufficient.
-
 Use `make dependencies` to map the native libraries to your system and fetch the remaining CLI dependencies to place them at the appropriate places.
 
-To compile OpenRA, run `make all` from the command line. After this one can run the game with `./launch-game.sh`. It is also possible to specify the mod you wish to run from the command line, e.g. with `./launch-game.sh Game.Mod=ts` if you wish to try the experimental Tiberian Sun mod. 
+To compile OpenRA, run `make all` from the command line.
 
-Type `sudo make install` for system-wide installation. Run `sudo make install-linux-shortcuts` to get startup scripts, icons and desktop files. You can then run the Red Alert by executing the `openra-ra` command, the Dune 2000 mod by running the `openra-d2k` command and Tiberian Dawn by the `openra-cnc` command. Alternatively, you can also run these mods by clicking on their desktop shortcuts if you ran `sudo make install-linux-shortcuts`. 
+Run with either `launch-game.sh` or `mono --debug OpenRA.Game.exe`.
 
-Arch Linux
-----------
-
-It is important to note there is an unofficial [`openra-git`](https://aur.archlinux.org/packages/openra-git) package in the Arch User Repository (AUR) of Arch Linux. If manually compiling is the way you wish to go the build and runtime dependencies can be installed with:
-
-```
-sudo pacman -S mono openal libgl freetype2 sdl2 lua51 xdg-utils zenity
-```
+Type `sudo make install` for system wide installation. Run `make install-linux-shortcuts` to get startup scripts, icons and desktop files. You can then run from the `openra` shortcut.

+	 * Activities are actions carried out by actors during each tick.
+	 *
+	 * Activities exist in a graph data structure built up amongst themselves. Each activity has a parent activity,
+	 * optionally child activities, and usually a next activity. An actor's CurrentActivity is a pointer into that graph
+	 * and moves through it as activities run.
+	 *
+	 * There are two kinds of activities, the base activity and composite activities. They differ in the way their children
+	 * are run: while a base activity is responsible for running its children itself, a composite activity relies on the actor's
+	 * activity-running code. Therefore, the actor's CurrentActivity stays on the base activity while it runs its children. With
+	 * composite activities however, the CurrentActivity moves through the list of children as they run.
+	 *
+	 *
 	 * Things to be aware of when writing activities:
 	 *
-	 * - Use "return true" at least once somewhere in the tick method.
-	 * - Do not "reuse" activity objects (by queuing them as next or child, for example) that have already started running.
+	 * - Use "return NextActivity" at least once somewhere in the tick method.
+	 * - Do not use "return new SomeActivity()" as that will break the graph. Queue the new activity and use "return NextActivity" instead.
+	 * - Do not "reuse" (with "SequenceActivities", for example) activity objects that have already finished running.
 	 *   Queue a new instance instead.
 	 * - Avoid calling actor.CancelActivity(). It is almost always a bug. Call activity.Cancel() instead.
-	 * - Do not evaluate dynamic state (an actor's location, health, conditions, etc.) in the activity's constructor,
-	 *   as that might change before the activity gets to tick for the first time.  Use the OnFirstRun() method instead.
-	 */
-	public abstract class Activity : IActivityInterface
+	 * - A composite activity will run at least twice. The first time when it returns its children,
+	 *   the second time when its last child returns its Parent.
+	 * - Do not return the Parent explicitly unless you have an extremly good reason. "return NextActivity"
+	 *   will do the right thing in all circumstances.
+	 * - You do not need to care about the ChildActivity pointer advancing through the list of children,
+	 *   the activity code already takes care of that.
+	 * - If you want to check whether there are any follow-up activities queued, check against "NextInQueue"
+	 *   in favour of "NextActivity" to avoid checking against the Parent activity.
+	 *
+	 *
+	 * Guide when to use which kind of activity:
+	 *
+	 * - The activity does not have any children -> base activity
+	 * - The activity needs to run preparatory steps during each tick before its children can be run -> base activity
+	 * - The activity or the actor is left in a bogus state when one of the child activities is canceled -> base activity
+	 * - The activity's children are self-contained and can run independently of the parent -> composite activity
+	 * - The activity does not have any or little logic of its own, but is just composed of sub-steps -> composite activity
