- Update DUMB to revision c0fc19ef2e756ef25aa44ca3775b4afed3f02c9c

Browse source 
- Changed aliased resampler loop conditions a bit to fix some bugs
    - Removed resampler loop unrolling, as it actually made things slightly slower
    - Fixed a bug with songs triggering notes on the first order with instrument changes before any note commands have been triggered
