Nick Briggs 66721ccc1c Replaces shadowed "-t <interval>" with "-timer <interval>" 
At some point option "-t" was introduced as an abbreviation for
"-title" but "-t" was already in use, though undocumented, for overriding
the timer interval.  This commit changes the command line timer option
to "-timer" and adds "timer" to the options that are processed from
the X11 resources.
