Bugfix: "Tweaking" Markers was working incorrectly

WM_modal_tweak_exit() was making incorrect use of the user-pref option
"Release Confirms Transform", indicated by confused coder comment
(<quote>"XXX: WTH is this?"</quote>).

This manisfested when moving markers by just click-dragging and
existing marker, and having it "drop" whereever the mouse was released
regardless of the user-pref option. This was quite confusing as it was
inconsistent with the way that all other transforms worked when this
option is off, where you would usually start the transform (click-
drag), release the button, move around a bit, and then finally click
to end.
