FMSLogo Code

Update to the latest revision from Andrzej Pruszynski.

Fix stray and missing double-quotes that prevented the Polish FMSLogo from compiling.

Add the missing NOT_YET_LOCALIZED comments that help track which changes I can overwrite and which ones I shouldn't. This corrects a mistake I made by copying the English version originally, instead of building the Polish version using mklocale.pl.

Correct some syntax errors in the Polish localized strings files.

Update to the latest revision from Andrzej Pruszynski. There are some syntax error that prevent the code from compiling, but I'll fix those in a subsequent revision. For now, I want to keep my corrections separate from his changes in the revision history.

Update the installer with the latest Polish translation from Andrzej Pruszynski.

Extend the code base to support a Polish translation, to be translated by Andrzej Pruszynsk.

Add logic to not show special variables in the editor's auto-completion list if it were defined by the user.

Add a missing "!= NIL" (for stylistic consistency)

Also remove some Windows-specific code in ledit() with code that compiles on all plaforms (by replacing GetEditorWindow() with one that returns a wxWindow, instead of an HWND)
