Analogue-sequencer

I've posted P3 v3.81 beta in the files section.
This adds an early implementation of 'direction', which you'll find 
in place of 'shift' in pattern edit. Shift has moved to a new page 
after cut/copy/paste.

The options so far are forward, reverse, and pendulum.
Forward is what it is.
For reverse, I'm still undecided whether it should start each 
pattern at the final step (as it is now) or at the first step.
With a 16th note pattern, starting at the final step is fine, but 
for eighth or quarter note patterns, they end up sounding off the 
beat, which isn't so nice. Easily changed tho'...
Pendulum plays alternately forward, then reverse.
A modified version of this might not play the first and last steps 
twice - I did it this way so that the pattern length is doubled, 
rather than being an odd number.
Comments welcome from those willing to experiment...
Random and brownian to be added shortly.

As a sneaky extra feature, you can manually over-ride the current 
direction by holding the RUN key while playing, and pressing one of 
the track keys - this +'s the current direction mode.
