Change fullscreen policies 

When a new client is spawned, fullscreen isn't disabled for all clients
in that monitor any more.

Instead, all fullscreen clients are kept fullscreen, while other clients
spawn in the background.

When fullscreen is disabled, all clients are rearranged.

This is made to make dwl more flexible allowing multiple fullscreen
clients at the same time, have floating clients on top of a fullscreen
one and let stuff happen without quitting fullscreen, like many other
WMs and DEs.
