Implement xdg-decoration

Browse source 
This commit adds a commandline switch (-d) to disable client side
decorations, if possible. In this case, Cage will not draw any
decorations of its own, in order to maximize screen real estate.

The default behavior remains the same, i.e., if -d is not passed,
clients will draw their client side decorations, if any.

Fixes #32
