During tab dragging if you hover over a browser window we now move it

to front after a delay. Also made docking to another window bring the
other window to front.

BUG=2038
TEST=Create two window with two tabs each. Drag a tab from one window
  onto the other window (not the tab area), hold it for a second and
  make sure the other window comes to front.
