[vdr] suggestion for timer-menu

[Guido Fiala <gfiala@s.netic.de>]

If a timer has a description field on can reach this by pressing ok,
however, in this menu no colored keys are displayed, no function available.

IMHO it would be suirtable to have the red button (edit timer) and the yellow  
button (delete timer) and blue button (on/off) at hands in this menu.

With "delete" the timer should be deleted and returned to the previous menu 
(timers).

Mainly the delete button is useful - after reading the description one decides 
that theshow isn't viewable and instantly likes to kill the timer, safes at 
least on keypress.

Also the patch the lets you search for other broadcast times of this show by 
pressing "0" could be active in this menu.
