Random Cleanup + OPDS Base Url Support (#1926)

* Updated a ton of dependencies. PDFs reader got a big update from PDF.js 2.6 -> 3.x

* Rolled back fontawesome update

* Updated to latest angular patch. Fixed search being too long instead of just to the end of the browser screen.

* Fixed alignment on download icon for download indicator in cards

* Include progress information on Want To Read API and when marking something as Read, perform cleanup service on want to read.

* Removed mark-read updating want to read. As there are series restrictions and it could be misleading.

* Tweaked login page spacing when form is dirty

* Replaced an object instantiation

* Commented out a few tests that always break when updating NetVips (but always work)

* Updated ngx-toastr

* Added styles for alerts to Kavita. They were somehow missing. Fixed an issue where when OPDS was disabled, user preferences wouldn't tell them.

* Wired up a reset base url button to match Ip Addresses

* Disable ipAddress and port for docker users

* Removed cache dir since it's kinda pointless currently

* Started the update for OPDS BaseUrl support

* Fixed OPDS url not reflecting base url on localhost

* Added extra plumbing to allow sending a real email when testing a custom service.

* Implemented OPDS support under Base Url. Added pagination to all APIs where applicable.

* Added a swallowing of permission denied on Updating baseurl in index.html for inapplicable users.

* Fixed a bad test
