FMSLogo Code

Fix a conjugation error (verb/subject number disagreement)

Add some line breaks to the example for HABILITALISTBOX.
This makes it clearer when you're supposed to look for what the example is showing.

Add some line breaks to the example for HABILITAVENTANA.
This makes it clearer when you're supposed to look for what the example is showing.

Fix a translation error in the example for LISTBOXDELETE

Replace "control de LISTBOX" with "control LISTBOX"

Translate the documentation for the LISTBOX* procedures into Spanish.
This translation was based on Rosario Ruiz's translation of the MSWLogo manual.

Undo the previous fix for Bug #518.

Bug #518 was that NUL glyphs would appear when typing Greek or Russian.
The underlying bug (Bug #522) was that wxWidgets was giving FMSLogo a NUL
character in the WM_CHAR handler. This was fixed, along with Bug #525,
which made FMSLogo suggest the wrong script for the fonts. With these
other two bugs fixed, the editors should work as expected for Greek and
Russian computers without using the stripped-down one used by the
Traditional Chinese version of FMSLogo.

Combine the ANSI Chinese/Greek/Russian tests into a single file.
Since files are read as a series of code points, there's no need to separate them into separate files.
The parts for the other languages look like gibberish in the source code, but won't be executed.

Fix Bug #523

The two-input form of KEYBOARDON once again outputs the correct code from KEYBOARDVALUE for non-Latin characters when called from the "keyup" instruction list. This was accomplished by refactoring the logic which gets the keycode to be called from both WM_KEYUP and WM_KEYDOWN.

Fix Bug #525; FMSLogo now suggests the system language as the default script for a font.

This fixes a problem where non-Latin users would have to configure their fonts specially to be able to type non-Latin characters (assuming they could figure out why they were typing gibberish). It also fixes a problem where LABEL would draw gibberish on the screen until SETLABELFONT was called appropriately (again, assuming someone knew the magic number to pass SETLABELFONT).

This change also replaces a few magic numbers with their symbolic names for a font's default.
