Allow edit of Override from show page

[GoogleCodeExporter]

Right now you have to edit the override page to add a show that isn't correct. 
For instance right now I record "The Looney Tunes Show (2011)". But mythepisode 
sees it as the former series, "The Looney Tunes Show". I added in the override 
and that gets The Looney Tunes Show (2011) on the page, but "The Looney Tunes 
Show" still shows up as well.  It would be nice to have some sort of "associate 
current recorded series with the correct series" link.

Add this to the override text file works, but still leaves the old entry and 
deleting the old entry from the shows directory doesn't work, it just gets 
recreated.

Meant override text file, not page.
