Link guideline
Added a new guideline for Performers and Studios under links section. It's worded in a way that it's strongly recommended, but is not reason enough to reject submission over it.
Avoid adding shortened links. If shortened URL redirects to a full link, use that instead.
Reasoning for it is simple:
- It leads to duplicate links. Very common case with links scraped from StashDB.
- Another case is that sometimes it excludes valuable information. E.g. ManyVids shortened links doesn't include performer ID, which can be used to lookup details even from defunct performers.
Also, https://docs.fansdb.cc/performers/#couple-type-accounts guideline was also re-worded to make it clearer without changing it's meaning.
