Swagger, Tachiyomi, and some new settings (#1331)

* Fixed up swagger generation

* Updated Tachiyomi's latest-chapter to hopefully solve some sync issues.

* Fixed #1279 with table of contents due to new EPubReader

* When errors occur, show the event widget icon in red

* Lots of documentation added and tweaked some wording around backups and swagger

* For promidius

* Return proper ChapterDTO

* Hacks for Promidius

* Cleanup code

* No loose leaf, send max chapter

* One more encode change

* Implemented code per promiduius' requirements

* Fixed a bug in the epub parsing where even if you had a series index and series group, but didn't have the series in the title, Kavita wouldn't group them properly.

* Removed some extra comment

* Implemented the ability to change a library's type after it's been setup. This displays a warning explaining the dangers of it.

* Removed some whitespace

* Blur descriptions based on read status for list item view to avoid spoilers

* Tweaked placement of a tooltip due to new series detail styles

* Hooked up a user preference for bluring unread summaries. Fixed a bug in refresh token where we would cause re-authentication when it shouldn't be needed.
