FMSLogo Code

Fix an assert failure in wxWidgets 3.1.0 when running "FULLSCREEN SPLITSCREEN" repeatedly within a line of execution (such that wxWidgets didn't destroy the old commander).

Ban the word "issue" and use "run" or "call" instead within the FMSLogo manual. "Issue" was used with exactly the same sense as these words and there's no reason to introduce a new word for an existing notion.

Further improve the performance of REPEATWORD by recursively applying the O(log N) strategy.

Improve the performance of REPEATWORD by doubling the word until the largest power of two under :repcount.

Remove an extraneous sizer flag that caused an assert failure in wxWidgets 3.0 whenever SELECTBOX was run.

Remove extraneous sizer flags that caused an assert failure in wxWidgets 3.0 whenever QUESTIONBOX was run.

Minor improvements to the documentation for POLYSTART and POLYEND:
* vertices made in PENUP mode are ignored
* clearscreen will erase any polygons
* used clearer, more direct wording

Fix bug #477; POLYEND now throws an error if the polygon has two vertices (same as if the polygon has one vertex).

This revision also includes many new regression tests for the polygon API.

Fix a reference to a bug number in the source code (the bug numbers changed when SourceForge.net was bought by DICE and they redid the database backend).
