1.0.2 - Small bugfixes, demo song tweaks

This is another quick update to address a couple of bugs:

• Fixed a bug where the sounds file and other preloaded files would throw a parser error on computers set to recognize commas as a decimal separator. (Because of how commas are used elsewhere in Pebble, only periods can be used as decimal separators, and the parser will now look for this format regardless of the region settings on the machine.)
• Fixed a bug where Set and Series would fail to stop properly when used with Sequences.
• Minor mixing adjustments to demo2 and demo3.
