[vdr] Patch #3: Return from commands menu

Hi list,

I'll be releasing this and a few other patches for VDR 1.3.33, which have evolved during the last months while working on XeatreOS (a distribution based on LinVDR 0.7, which is used for the Xeatre boxes, http://www.xeatre.tv/). Some of their functionality may already be included in plugins or other patches. Nevertheless, I'd like to release them now, and let everybody decide whether they are useful or not.

This patch modifies the commands menu. After a command with output is executed, when the user presses Back, VDR jumps back to the recordings menu instead of the commands menu. This was a customer's feature request :-).

Greetings, Sascha Volkenandt
