FMSLogo Code

Implement part of request #1542399; FMSLogo is no longer limited to 1024 turtles.

Add a regression tes for bug #1959250, which is that SETBITINDEX has side-effects when given bad input.

Implement part of request #1542399; FMSLogo is no longer limited to 1024 turtles.

Add a test for when allocating the array fails.

Implement part of feature request #1542399; remove 1024 limit on total turtles. Now the total number of turtles that you can allocate is limited only by the amount of memory available to your system.

This change reduced the overall size of fmslogo.exe by about 150 KB.

Refactor the g_Turtles array into g_Turtles and g_SpecialTurtles so that the special turtles aren't at the end of the array. This was done to make it easier to implement feature request #1542399, which is to remove the hard-coded limit on turtles. Keeping the special turtles in a separate array, rather than at the end of the g_Turtles array will make it easier to dynamically resize the array.

Interestingly, this caused a 80KB increase in the size of the binary. I'm not sure why.

Add regression tests for RANDOM and RERANDOM.

Implement feature request #1947327; link the documentation for RANDOM to RERANDOM.

This also updates the version in FMSLOGO.TXT to 6.21.0.

Implement feature request #1947327; link the documentation for RANDOM to RERANDOM.

While I was at it, I described how RANDOM works, so that programmers will understand what setting the random seed does.
