[dev] [dwm] exit fullscreen correctly

[Andreas Amann]

dwm does not always leave the fullscreen mode correctly. 

For example, if you use the mouse to resize a fullscreen client, the boarder
does not get painted, which indicates that internally the isfullscreen flag
is still set.  A similar effect happens if togglefloat (Alt-Shift-Space) is
applied to a fullscreen client. 


The attached patch fixes this.
