VDR Block Plugin

HISTORY excerpt:

Added a new detection method: Channel EPG
This method scans the running program and not only blocks on zapping but
also makes the plugin switch to another channel on a changeover to a
blacklisted show. In some rare cases several stations do not update
the current EPG signal in sync so unfortunately there might be false
detections. It is possible to change the detection method in the plugins
setup, where 'On Switch' is the old method and 'Channel EPG' the new.

Furthermore it is now possible to change switching directions on a block
event by pressing the (channel) up/down keys on your remote.

Several other minor code changes.
