Add support for XUrgency and matching _NET_WM_STATE_DEMANDS_ATTENTION

ewmh hint; urgencyborder is configurable.  The urgency flag will stick,
even while on a client in a non-viewable group, until the client
receives focus (where the border is reset).  Initial diff from Thomas
Adam with some changes/enhancements from me.
