[Feature] Distributor vs Studio vs Production Company

[LeeThompson]

I know this is a murky subject for porn, especially in the 1970s, studios would leave their names off and make up names for credits. Eventually, it did get a bit more legit so it's possible to even have the production company, a studio that does the editing/post production work, and then a distributor.

Sometimes distributors change over time, for example:

The 1976 film "All Night Long": Studio/Production: Essex Pictures Company Distribution: Vinegar Syndrome (Current, Restored Edition), Alpha Blue Archives (Previous), Essex Video (Original)

My feature request is:

• For "Studios" add a "Type" field [ "Production", "Studio", "Distributor" ]
• In "Scenes" and "Movies" allow multiple studios to be specified.
• Movies could have an additional field for this particular release such as "DVD" "Reissue" "Restored" etc. (or let us have custom fields).
• Movies should also allow at least 2 dates, the initial release date and the current release date. With the above film, using the adultdvdempire plugin, acts like the film was released in 2018 (and as far as the Vinegar Syndrome release, that is somewhat true), but the actual production/original release was 1976. The original release could just be a four digit year as most adult films don't have an exact release date since they would move from city to city instead of having a 'wide' release.
