Add facitility for Global Keyboard shortcuts.

Also, do some housekeeping for our current shortcuts.

* Command-Option-l - Downloads [same shortcut as Safari].
* Command-Shift-[/] - Back/forward tab.
* cntrl-pageup/pagedn - Back/forward tab.

Global Keyboard events are intercepted by a new BrowserWindow custom class.

BUG=12537,15486
TEST=Check that above keyboard shortcuts work as advertised.
