Tidying Up the Database

A couple of suggestions to help out contributors:

1. There are many orphaned profiles. These are usually created due to a credit being renamed to another profile leaving the original one empty. Could I suggest that if a profile has no credits or bio whatsoever for more than a year, the profile is purged. When adding a person to a production, many of these empty profiles pop up. When it's someone with a very common name, this can cause the genuine profile to not appear in the rather short list of possible profiles.
2. There are many series that haven't officially ended, but aren't coming back.... ever. If a series hasn't had an episode added in more than 5 years, mark it as ended. In the rare event a series returns after a long gap, adding an episode will reinstate its status.
3. Similarly to #2, If a production has been marked as being "In Production" for more than, say, 5 years, it's probably no longer in production. Perhaps automatically mark these as "completed, but not released" (or similar).
