Manga Reader Refresh (#1137)

* Refactored manga reader to use a regular image element for all cases except for split page rendering

* Fixed a weird issue where ordering of routes broke redireciton in one case.

* Added comments to a lot of the enums and refactored READER_MODE to be ReaderMode and much more clearer on function.

* Added bookmark effect on image renderer

* Implemented keyboard shortcut modal

* Introduced the new layout mode into the manga reader, updated preferences, and updated bookmark to work for said functionality. Need to implement renderer now

* Hooked in ability to show double pages but all the css is broken. Committing for help from Robbie.

* Fixed an issue where Language tag in metadata edit wasn't being updated

* Fixed up some styling on mobile for edit series detail

* Some css fixes

* Hooked in ability to set background color on reader (not implemented in reader). Optimized some code in ArchiveService to avoid extra memory allocations.

* Hooked in background color, generated the migration

* Fixed a bug when paging to cover images, full height would be used instead of full-width for cover images

* New option in reader to show screen hints (on by default). You can disable in user preferences which will stop showing pagination overlay hints

* Lots of fixes for double rendering mode

* Bumped the amount of cached pages to 8

* Fixed an issue where dropdowns weren't being locked on form manipulation
