v1.1.1 - Some Bug Fixes

This is a handful of fixes for bugs I've run into while working on a larger song project. I've also been working on expanding the fonts to include Unicode's Latin-1 Supplement, but I've decided go ahead and roll out the bug fixes now, because it'll take me a bit to make all the new glyphs for each of the 5 fonts.

Here's what v1.1.1 includes:

• Fixed an incorrect Parsing Error message relating to the new COPY property.
• Fixed a crash when trying to parse empty Patterns, Sets, and Series'. This will now display an error message instead of crashing the program.
• Fixed a bug in MIX where stopping a Sequence early would sometimes cause it to play an extra note from the next step in the pattern.
• Fixed a bug with Sets where the active module could switch when the Set was copied, which sometimes caused unintended behaviors (like retriggering) when the Set module or its parent was halted.
• Changed the render output format from WAV Extensible to WAV PCM (the more common/compatible format).
