The new tab button mouse enter is handled in the tab strip controller to ensure
an accurate hover indication (the button is an odd shape).

XIB Changes: Update the new tab button's cell class to the new NewTabButtonCell.

BUG=104326
TEST=Hover over the new tab button, it should light up. Hover slightly to the right of it, it shouldn't light up.
