key: early support for XK_m modifier to chase focus

Particularly on large multi-head display setups it can be
annoying to have to find the mouse pointer after long periods of
not using it, on the rare occasion one must bring it to the
currently focused window to do a pointer operation.

This commit introduces XK_m for controlling a "chase_it" flag,
which future commits will utilize for augmenting focus-changing
operations, and maybe window configuring operations, by warping
the pointer to the center of the focused window /after/ the
augmented operation has been performed.
