Vht

new in this release:
- backups
- drawing line in velocities (shift)
- more work on hints
- controller cache
- holding panic
- loads of bugs

- cleaned up shortcuts in timeline
- local seq looping
- doubling/halving of strips
- replacing main seq from strip
- man-page
- loads of little bugs

Fixed some urgent issues that came up after first release (surprise, surprise)

notably:
- rendering will no longer hang when exiting freewheel
- sequence triggers (play:hold)
- a typo in shortcuts screen (now it's even more)
- controllers/envelopes reaching beyond tracks

Will try to concentrate on documentation now

The first version that kind of seems to do what was intended, hence the first public release. Hope you will have more fun exploring it, than I will have writing documentation for it. Consider this alpha quality software, probably won't turn you into a new Jean Michel Jarre or Scrillex so don't give up your daytime job just yet. First of all, have fun!
