[dev] Hide border in monocle mode

[Bjartur Thorlacius]

Attached is a unified patch against tip for hiding the border of clients when 
in monocle mode. A border is still drawn when in tiled mode, even if there's 
only one client visible. That's unuseful but as a passive reminder of the 
current mode. This behaviour is a compromise stemming from the border drawing 
handler being less accessible.

The patch is makes the same change to both resizeclient() and configure(). This 
is especially awkward considering that resizeclient() calls configure().
