FMSLogo Code

Add benchmarks for 6.19.0.

Fix a typo.

Fix bug #1551634; Integrate some MCI examples into the manual and remove the "Help -> MCI" and "Help - Using Help" menu options to remove final remanants of the defunct .hlp format.

Removing mcistrwh.hlp has a few benefits. First .hlp files are not supported on Vista. They are also not supported on GNU/Linux, so this could have been an impediment to porting FMSLogo to GNU/Linux. But the most significant reason is that I was unable to locate a copyright for mcistrwh.hlp and therefore could not prove that its license was compatible with the GPL. Distributing this file put both FMSLogo and SourceForge at unnecessary legal risk.

Update the system requirements in some examples. It looks like they hadn't been updated in over 15 years (one of them referred to Windows 3.1, which is not supported).

Add some examples on how to use the MCI command to perform common tasks.

Add some logic for creating only one workspace editor window. The design was taken from the Borland OWL-based implementation of FMSLogo.

Remove an unused "#include <windows.h>". I'd rather not use platform-specific headers when it can be avoided.

Get the wxWidgets version of FMSLogo to compile on my Fedora Core 8 box, again.

Centralize the logic for getting/setting platform-specific font information from/to persistent storage. The logic is a bit clumsy, so I don't want to copy and paste it throughout the code base.

Add logic for setting the font Editor's font.
