autofocus urgent tabs

When tabbed becomes urgent because one of it tabs becomes urgent, it
may be desireable to automatically focus that tab. As a notification may
be lost, if another notification comes in before you focused tabbed, the
switch is only done, if tabbed is not urgent already.
Moreover, it may be anoying, if you just type into one tab, another tab
gets urgent -therfore focused- and you type into the other tab, you may
switch between autofocus and nofocus using Ctrl-Shift-u.
Maybe it would also be usefull, if there would be an commandline
parameter to toggle that option, but as -u is already used for
urgent-tab-color, i did not implement that.
