Add support for background blur

Browse source 
This patch adds a new config option: colors{,2}.blur=no|yes. When
enabled, transparent background are also blurred.

Note that this requires the brand new ext-background-effect-v1
protocol, and specifically, that the compositor implements the blur
effect.
