Subject: Support disabling WM support (#45)

Most people profit from a bar that supports multiple compositors.
But some (like me), depend on special features of a compositor and as such
only ever use one of the supported compositors. Being able to disable support
for the others, at compile time, allows them to remove dead code from
their system.
