[mythtv] [PATCH] Verson 2 - Duplicate Detection Methods

[Joel Feenstra]

Here is version two of a patch that adds the ability to detect 
duplicates based on title+subtitle, title+description, none(eg always 
record), title+subtitle+description. It's implimented in two fields as 
suggested by Chris Pinkham and others. I've also changed the database to 
use two fields, dupin - which is where we look for duplicates, and 
dupmethod - which is how we check for them. I've also rearanged the 
advanced recordings screen a bit. To allow the recorded programs to be 
associated with a record in the "record" table, I've added a recordid 
field to the "recorded" table. This is used to get the dupin and 
dupmethod from the record table. In other words, you can alter the 
record table and when you go to delete a program, the "Yes, but record 
this episode again next time" should show up correctly.

Obviously wait to apply until after .14 comes out. Tell me if I'm 
forgetting something. I'm not that knowledgable about the source code. I 
did change the PROTO setting in mythcontext so that should be good.

Pre-existing shows will not be associated with their "record" table 
record, but they will use the current method by default.

Comments are welcome. Thanks for the great work thus far.
