OmniConverter PR - 1.0.0 r37

Changelog:

• Updated BASS libraries, and added BASSFLAC (to fix issues with some SFZ using FLAC samples, where certain opcodes get ignored, thanks @minelolpride for the bug report through OMv2!)
• Fixed broken SysEx support. This should make stuff like master volume and GM/GS/XG SysEx chains work.
• Various improvements that do not deserve to be mentioned here.
