FMSLogo Code

Fix Bug #558; SETLABELFONT once again prints the names of each font when the font family name isn't supported.
This was a silent regression introduced by porting FMSLogo to Unicode. The old format strings used "%s" which is for "char*" string, but the new strings are "wchar_t*", so only the first character was printed. The fix was to use "%ls".

Make FONTFACENAMESTEST.SMOKETEST locale-independent

Update the version to 8.0.1 for a formal release.

Fix the documentation for WINDOWSET mode=7.
This doesn't restore the window, but rather minimizes it window (SW_SHOWMINNOACTIVE).

Note that I've improved the manual in 8.0.1.

Add an example to THROW that shows how to test for bad input.
This was motivated by an online conversation with Manfred Zindel where he explains that he wasn't able to figure out how to do so by reading the manual.

Simplify LOCALVARTEST:
- Replace 'RUN (WORD ": :varname)' with THING.

Fix Bug #557; FMSLogo no longer crashes when it is closed while processing instruction list callbacks.

This is an unsatisfying fix, as I wasn't able to find a single place to check if the main frame has been deleted before processing an event. Instead, I put it in a few places that I was able to find that led to dereferencing NULL. It's possible that adding it to do_execution would have been sufficient or that I should add it to more places.

In any event, this fixes the crashes that I was able to reproduce reliably (MOUSEON and WINDOWFILEEDIT).

Cleanup: Remove commented out code

Simply EDITTEST.MANYVARIABLES:
- Replace FOR with REPEAT
- Replace a LOCALMAKE with MAKE (the variable was already LOCAL)
- Remove the "testpassed" flag
