Switch to the post search engine using the new PostQuery parser. The new
engine fully supports AND, OR, and NOT operators and grouping expressions
with parentheses.
Highlights:
New OR operator:
* `skirt or dress` (same as `~skirt ~dress`)
Tags can be grouped with parentheses:
* `1girl (skirt or dress)`
* `(blonde_hair blue_eyes) or (red_hair green_eyes)`
* `~(blonde_hair blue_eyes) ~(red_hair green_eyes)` (same as above)
* `(pantyhose or thighhighs) (black_legwear or brown_legwear)`
* `(~pantyhose ~thighhighs) (~black_legwear ~brown_legwear)` (same as above)
Metatags can be OR'd together:
* `user:evazion or fav:evazion`
* `~user:evazion ~fav:evazion`
Wildcard tags can combined with either AND or OR:
* `black_* white_*` (find posts with at least one black_* tag AND one white_* tag)
* `black_* or white_*` (find posts with at least one black_* tag OR one white_* tag)
* `~black_* ~white_*` (same as above)
See 4c7cfc73 for more syntax examples.
Fixes#4949: And+or search?
Fixes#5056: Wildcard searches return unexpected results when combined with OR searches
Inline the page footer, news updates, the ban notice, and the user
verification notice into the default layout. This is a micro
optimization to reduce the number of spans reported to the APM.
Don't show deprecated tags in the related tags or translated tags lists
when editing a post. It doesn't make sense to recommended adding tags
that can't be added to the post.
* Deprecated tags can't be added to posts, but existing deprecated tags
in a post won't be removed
* Only empty tags can be marked as deprecated manually
* No tags can be manually undeprecated
** These limits don't apply to admins
* Deprecating or undeprecating a tag will create a new mod action to
prevent people from going rogue
* Added deprecate/undeprecate commands for BURs
* Deprecating a tag via BUR removes all implications to and from it as well
This is necessary for the `commentary:` metatag, which has different
behavior depending on whether the metatag value is quoted. For example,
`commentary:translated` finds translated commentaries, while
`commentary:"translated"` finds commentaries containing the literal word
"translated".
Count the number of commented and noted posts directly, instead of
indirectly by counting the number of posts in a `commenter:<name>` or
`noteupdater:<name>` search. This is faster because it generates
better SQL.
