FMSLogo Code

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.

This commit was manufactured by cvs2svn to create tag 'VER-6-20-0'.

Update one more time for the 6.20.0 release. I found a bug late in my test pass and added a new regression test for it.

Add some more tests for FOREACH to catch a regression in pacturtle that I introduced when I fixed #1669735.

Try another fix for bug #1669735. The previous fix had some problems when the data list was a variable and it output something. I think the problem was not with my fix, per se, but that my fix hit a different bug in RUN.

This fix is a little slower, but it seems to work around the other bug in RUN.

Update the expected test log based on the results from 6.20.0.

Update the expected version for the 6.20.0 release.
