oga cdb45f007b We've been handling grabbing wrong all this time (noticed at c2k8). 
add conf_grab() and conf_ungrab, and use them in the keybinding manipulation
functions to {,un}grab the binding for all screens we have defined.

the lovely little ordering problem comes in here, since when we parse
the config initially Screenq is empty, so regrab after we fill the
queue, hopefully later reordering will remove this little need and there
will be much rejoicing.

ok okan.
