bell: optionally render margins in red when receiving BEL

Add anew config option, ‘bell=none|set-urgency’. When set to
‘set-urgency’, the margins will be painted in red (if the window did
not have keyboard focus).

This is intended as a cheap replacement for the ‘urgency’ hint, that
doesn’t (yet) exist on Wayland.

Closes #157
