Added undocking if necessary to start of supercruise assist.
Removed speed demands from the nav alignment code. Nav align should just do the alignment, the calling function determine what to do if alignment is successful or not. All but one of the calling routines sets the speed after calling the routine anyway.
sc_assist no longer spams 50% speed every iteration of its loop. So pilot is free to control the speed and just let AP do the alignment. Works great for manual 75% throttle at 0:07 from target and when using new SCO in SC.
sc_target_align now returns false if the target was found and now is lost and as no other cause was captured, then we went past the target.
While in SC, if we fly past the target, keep going for 5 secs, then slow to 50% and turn around using nav_align.
