FMSLogo Code

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)

Extend the auto-completion logic to include suggesting completions for variable names.

Update the old SourceForge bug numbers to the new ones (after a SourceForge upgrade each project was given a private numberspace for its bugs).

Minor cleanup to CLocalizedNode:
- Add comments
- Rewrite GetName() in terms of GetNode()
- Change a NULL to NIL, since it referred to a NODE*

Fix a problem with the AutoComplete popup in the commander input control where, if you pressed the up arrow in the AutoComplete popup, the focus would be given to the history box, instead of moving the selection in the AutoComplete popup.
