[Patch] add awful.mouse.wibox.move()

[Gregor Best]

Hi people,

during the last few days, i got some time to fiddle around with awful.mouse
This fiddling let to the creation of awful.mouse.wibox.move(), which lets the
user move the wibox under the pointer (or the supplied one) similar to
awful.mouse.client.move(). If the user drags the wibox to one side of the
screen and it is not floating, its position is changed instead.
