Add the ability to resize the window when over the custom frame.

I also switched from 3px borders to 4px borders because that's what they are
on windows.  On linux, the borders look bigger because our webcontent area
doesn't drop a shadow.

For this to work for resizing on top, I had to remove the event box from
the browser titlebar and move the mouse event handling to the window.
