FMSLogo Code

Fix bug #1327711; Instructions run by GUI elements now also write to dribble file.

This was done by extracting part of the function called by the "Execute" button and moving it to RunLogoInstructionFromGui(), then calling this function from all of the GUI elements that write to the commander's recall box.

Fix a bug where you could move through a line if you moved through it near the endpoint. Now a tolerance of 1e5 is allowed for floating point precision.

Fix the cosmetic bug where crashing in one move reported the crash as "1 moves". Now it is correctly reported as "1 move".

Add commands that have the same name as the RESET and NEXT buttons, for convenience.

Add "turtlemaze" a game for basic movement commands.

Add regression tests for SLOWDRAW.

Add a regression test for bug bug #1577526; we now test that SLOWDRAW buries the commands which it defines.

Fix bug #1577526; SLOWDRAW now buries the commands that it defines

Centralize the logic for untreeifing a proc node. Also fix some memory leaks related to not untreeifying proc nodes when the get redefined/copied.
