[vdr] Interactive plugins and MENUTIMEOUT since 1.3.32

[rollercoaster at reel-multimedia.com]

Hello List,

in 1.3.32 the timeout of the menu is now handled in the main loop (vdr.c).
this causes some plugins (in this case: channelscan) to be closed after 
MENUTIMEOUT what is sometimes not wanted...

One way would be to make LastActivity global and update it in the plugin, 
another way would be to introduce a variable e.g. "AutoCloseMenu" in 
cOsdObject...

Is there an "intended" way to suppress this behaviour? 
Any suggestions?

regards,
Thiemo
