* Use Rails tag API to build RSS feed for spoilers and polls
While the previous method did not contain a bug or a potential issue,
the tag API can be very resilient against future problems and reduces the
amount of manual management of the escape status of the content.
I've added tests to ensure that the formatting is broken and still
escapes control characters correctly.
* this seems cleaner and passes
* Incorporate feedback by moving the br to its own line and using the tag helper over the string constant for the br tag itself
* whoops, tag helper doesn't use a self-closing tag
* Change RSS feeds
- Use date and time for titles instead of ellipsized text
- Use full content in body, even when there is a content warning
- Use media extensions
* Change feed icons and add width and height attributes to custom emojis
* Fix custom emoji animate on hover breaking
* Fix tests
