FMSLogo Code

Add in the changes for 6.20.0 for the next release.

Bump the version to 6.20.0 for the next formal release.

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.

Add support for setting the label font from the main menu. Of course, this doesn't actually do anything, yet, since the LABEL command (or any other Logo commands) have no been implemented.

Add benchmarks for 6.19.0.

Fix a typo.

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.
