Enhance Tocs

[mytlogos]

PRO:

• Less changes from contradictory tocs
• Delete releases (and maybe episodes) which do not occur in toc anymore
  • Against spam episodes
  • against invalid scraped chapters which were fixed later (no more manual removals!)

CON:

• How to resolve the it when displaying in client? (which available properties wins?)
• More resources needed to save it (up to 300% of media space, atm + ~7MB?)
• More resources needed to enforce it (should be doable, as there is enough ram and maybe cpu)

TODO:

• Add Properties of medium to medium_toc
• Add new Primary Key to medium_toc and previous to unique index
• Add referenced toc_id column to episode_release
• Updates medium_toc instead of medium when scraping tocs
• User updates medium only, not medium_toc properties (only the crawler should do that)
• tocs releases are validated every toc job
  • releases are assigned a toc id if first seen
  • releases with toc ids which do not occur in a toc job anymore are removed (and their episode maybe too)
  • what is with toc releases without toc id which are currently invalid?
