moved processKey after process was called, to have always a fresh buffer for key calculation
Add beat jump support. Fixes Bug #910617.

* Works fine with master sync.
* Supports same jump lengths as beatloops.
* Added tooltips and MIDI learn descriptions.

New deck/sampler controls:
[ChannelX/SamplerX],beatjump
[ChannelX/SamplerX],beatjump_%1_forward
[ChannelX/SamplerX],beatjump_%1_backward
Change [ChannelX],beatloop control to a ControlObject instead of ControlPushButton.

This control isn't a button so it shouldn't be a CPB.
