OPDS Support (#526)

* Added some basic OPDS implementation * Fixed an issue with feed href * More changes * Added library routes and moved user code to a method so we can hack in fixed code without authentication * Images now load on the OPDS reusing our existing Image infrastructure. * Added the ability to download and moved some download code to a dedicated service * Download is working, pagination is implemented. * Refactored libraries to use pagination * Laid foundation for OpenSearch implementation * Fixed up some serialization issues and some old code that wasn't referencing helper methods * Ensure chapters are sorted when we send them over OPDS * OpenSearch implemented * Removed any support for OPDS-PS due to lack of apps supporting it. * Don't distribute development.json nor stats directory on build. * Implemented In Progress feed as well. * Ability to enable OPDS for server. OPDS now accepts initial call as POST in case app uses username/password. * UI now properly renders state for OPDS enablement. Added Collections routes. * Fixed pagination startIndex on OPDS feeds when there is less than 1 page. * Chunky Reader now works. It only accepts UTF-8 encodings * More Chunky fixes * More chunky changes, such a fussy client. * Implemented the ability to have a custom api key assigned to a user and use that api key as your authentication token against OPDS routing. * Implemented the ability to reset your API Key * Fixed favicon not being sent back correctly * Fixed an issue where images wouldn't send on OPDS feed. * Implemented Page streaming and fixed a pagination bug * Hooked in the ability to save progress in Kavita when Page Streaming
