Add user interface for scrubbing and Experimental.h switches

Browse Source 
EXPERIMENTAL_SCRUBBING_BASIC enables middle-click-drag to scrub, or to seek
when shift is down.

EXPERIMENTAL_SCRUBBING_SMOOTH_SCROLL adds middle-double-click-drag to
scrub or (with SHIFT down) to seek while keeping the playhead at the midline
of the track display.

EXPERIMENTAL_SCRUBBING_SCROLL_WHEEL allows control wheel to vary the speed
limit, while scrubbing (not seeking).

All three are enabled in this commit.

Also notice the changes to status bar messages and the Mouse Preferences dialog.

Scrubbing works only in Select and Multi tools.
