Replaced GetCwd() with wx.wxStandardPaths.Get():GetExecutablePath() as the
former doesn't return proper unicode path (at least in wxlua 2.8.12.2).
Replaced io.open with wxFile operations and disabled default error reporting.
Replaced os.rename with wxRenameFile.
Added support for unicode in dofile for Lua (replaced unicode names with
short names using winapi).
Fixed navigation in the Output window to recognize unicode file names.
Upgraded to MobDebug v0.485 to make debugging/breakpoints/step work for
files with unicode paths.
