* [chore] Remove years from all license headers
Years or year ranges aren't required in license headers. Many projects
have removed them in recent years and it avoids a bit of yearly toil.
In many cases our copyright claim was also a bit dodgy since we added
the 2021-2023 header to files created after 2021 but you can't claim
copyright into the past that way.
* [chore] Add license header check
This ensures a license header is always added to any new file. This
avoids maintainers/reviewers needing to remember to check for and ask
for it in case a contribution doesn't include it.
* [chore] Add missing license headers
* [chore] Further updates to license header
* Use the more common // indentend comment format
* Remove the hack we had for the linter now that we use the // format
* Add SPDX license identifier
This changes parseDescription to properly encode things to be safe for
usage without removing things like backslashes that may be relevant.
* text.SanitizePlaintext already calls html.UnescapeString so we don't
have to do that
* Replace \n with space early
* Remove duplicate white-space by splitting on fields and joining
* HTML-escape the string we have
* For extra certainty, encode the backslash as \
Fixes#1549
* f0x gitignore additions
* better meta title and descriptions
* user avatar icon for thread and profile meta tags
* use proper tag for image
* whitespace
* add noescapeAttr template function
* use ogMeta struct for opengraph
* maxOGDescriptionLength = 300
