Issue: Option to "Disable" Caching

VaultWiki usually tracks wiki links for statistical use on Special pages, among other things. However, with the number of posts typically on big boards, this can become a daunting feature with extremely slow queries.

For the next build, added an option to disable caching.

Redirects and templates will still be cached in wiki articles, but all other links will be ignored. Additionally, they will not be cached when the article is saved, only when the article is parsed by someone visiting it. This will likely cause statistical delays, but it really speeds up saving.

Special pages that rely on this information will not be listed - one of these is Whatlinkshere aka "List of Links". If the direct link is known, it will show an error message that the info is missing.
