Keymap: Add additional scrubbing affordance (Alt-LMB)

This adds an additional way to scrub the playhead, by holding Alt and dragging with the left mouse button, in addition to Shift-RMB.

It's easier to do this, especially with pen input. The other method is still kept, in case you have Emulate 3 Button Mouse enabled, in which case Alt-LMB pans the view

And of course, you can still scrub simply by dragging the playhead, without holding any modifier keys.

Right click select is unaffected.
