Analogue-sequencer

Folks,

v3.90 is in the files section now.
The user manual is also now up to date - including the section on 
aux events and accumulators.

I'm not intending to add any more new stuff for a few weeks now, as 
I have some other stuff to do (i.e. get married two weeks on 
Saturday).
I'll do any essential bug fixes, but this should be it until I get 
back from the Mayan riviera ;-)

Cheers,
Colin f
