FMSLogo Code

Add logic for copying the currently selected item in the commander history to the commander input.

Add the wxWANTS_CHARS style so that directional keys are passed to OnChar(). This enables the MSWLogo-style commander navigation.

Add a missing newline to a printf diagnostic.

Eliminate a string copy in reader() to try to make it a little faster. Performance tests show a small improvement in the benchmark for READWORD, but that may just be randomness.

Remove CDynamicBuffer::GrowTo() because it was never used.

Do some minor code tightening in reader() to make READWORD a little faster.

Fix bug #1900691; Whitespace after ~ is now preserved when the ~ is not a continuation character.

Integrate all tokenization conformance tests from The Great Logo Atlas 0.57.

Improve RUNPRINTTEST so that it can handle instructions that print multilpe lines. This was necessary to integrate the tokenization tests from The Great Logo Atlas.

Formally thank Pavel for his contribution. He reported a bug and contributed some regression tests for the parser.
