Make cwm default keybindings always exist. Additional keybindings now

overlap with the new ones, overriding them. Also a new "unmap" keyword
in binding definitions now unmaps a binding without adding a new one.

This seriously shrinks the ~/.calmwm/.keys directory of anyone who defines
their own bindings whilst wanting some of the defaults.

Looked over, liked and ok todd@
