Continue works on loop points and some clean-up

- Added more detailed error information while parsing MIDI file
- Added abiltiy to retrieve loop points time positions
- Added ability to change playing tempo by giving multiplier
- Removed old commented code

TODO:
- implement meta-information store and a way to retreive it
- implement hook-ability for every MIDI event
- implement ability to mute/solo every channel
