* Refactored the way cover images are updated from SignalR to use an explicit event that is sent at a granular level for a given type of entity.
Fixed a bad event listener for RefreshMetadata (now removed) to update metadata on Series Detail. Now uses ScanService, which indicates a series has completed a scan.
* Lots of attempts at making webtoon stable. Kinda working kinda not.
* Added a new boolean to hide images until the first prefetch loads the images, to prevent jankiness
* On Search, remove : from query
* Added HasBookmark and NumberOfLibraries to stat service
* Cleaned up some dead code
* Fixed a bug where page number wasn't reset between chapter loads with infinite scroller
* Added recently added series back into the dashboard.
* Cleaned up some code in search bar
