removed start/end positions.. cleanup

sort of weird thing with at_bar going on, gonna try to fix that
beats per bar, 4 even if we're a seconds type.. in case we change
types..
retabbed
removing position from player as much as we can.. need to fix rate
syncing
resync working, not ideal with speed shifts though
much better sync to transport.. sync to player now broken
fixed sync to player.. GREATLY improved sync to transport

working really nicely
removing more position stuff from player
