Well, originally I wanted the events to be left exactly
as they came off the air if the bugfix level is 0.
However, events that don't even have a title make no
sense, so they shall always have one.

cEvent::SetTitle() is probably not a good place for this,
because it isn't guaranteed to be called at all.

The only real good place to do this would probably be the cEvent
constructor, but that would mean setting the title to something
that in 99.9% of all cases will be overwritten.

Since cEvent::FixEpgBugs() is called for all events that are
broadcast, it now makes sure every event actually has a non-NULL
title. The only loophole left is SVDRP's PUTE command, but the
man page states that "every event should at least have a T entry".
Maybe I should make that a "must".
