Option for clock and timer to be displayed in frame-title
* org-clock.el: New option `org-clock-clocked-in-display' to control
whether the current clock is displayed in the mode line and/or frame
title.
* org-timer.el: New option `org-timer-display' to control whether
the current timer is displayed in the mode line and/or frame title.
This allows the clock and timer to be displayed in the frame title instead of,
or as well as, the mode line. This is useful for people with limited space in
the mode line but with ample space in the frame title.
