[mythtv] quirk with Record One Showing Daily

[George Nassas]

First off, many many thanks for this feature. It has saved me from the 
oodles of manual shuffling I used to do.

The quirk I've noticed is with a program I record that has its "fresh" 
showing each weekday at 8pm with a rebroadcast the following afternoon. 
Monday afternoon's showing is a repeat of Friday evening but because > 
1 day has passed the scheduler fails to associate the two and I get an 
extra Friday. There are no episode descriptions so duplicate matching 
that way is out.

Deleting one duplicate episode a week is better than before but, of 
course, having it all would be so much nicer.

The obvious solution is to add a "Record One Showing Each Weekday" / 
kFindWeekdayRecord option to the RecordingType enum and fill in the 
relevant behaviour in the scheduler ( which I'm not sure how to do yet 
=)

If the powers that be feel that this is a good approach I'm happy to 
jump in there and take care of it.
