Changelogs - BEEmod Music Package Creator

Added support for adding custom speed and bounce gel SFX
Added BACK button in package creation window to allow going back to previous stages
Improved UI visuals for list of added songs when creating a package
Fixed validation which allowed adding a song without selecting base music
Minor fixes and changes

Added support for adding multiple songs per single package
Added the ability to specify group name for music per single package
Updated and optimized audio encoding engine
- BMPC v1.1.0 now compresses music files with Microsoft ADPCM WAVE format, instead of uncompressed 16-bit PCM, which greatly reduces file size while still keeping the quality and benefits that WAV files bring
- Loop points are still added automatically as part of the encoding process
- This also poses as a fix to issues happening with music that's long (or is high in file size) which caused the game to become unstable, start lagging, not playing funnel music or not playing any music at all or having issues with publishing the level - Source engine does not like large audio files
