Subject: Add BorderUrgencyHook to XMonad.Hooks.UrgencyHook

Ignore-this: 9fac77914ff28a6e9eb830e8c9c7e21e
BorderUrgencyHook is a new UrgencyHook usable with withUrgencyHook or
withUrgencyHookC; it allows an urgent window to be given a different
border color.  This may not always work as intended, since UrgencyHook
likes to assume that a window being visible is sufficient to disable
urgency notification; but with suppressWhen
