Add "Start immediately" option to STSP

[mgd]

Just like the CBPB 0xx/1xx command can either be active with upon the next queue point or immediately I would like to add a similar option to the STSP command. This would be a very convenient way to resync tracks that have been playing at different tempos/clock divisions. For a moment I had thought CBPB 8xx would do the job, but that one doesn't start on the first step.
So basically I want the STSP 0xx changed into STSP 00xx and the new STSP 10xx for an instant jump (and of course the 1txx with t = 1..8 for the track number)

Kind regards,
Michael
