Automatic Collection Creation (#1768)

* Made the unread badges slightly smaller and rounded on top right.

* A bit more tweaks on the not read badges. Looking really nice now.

* In order to start the work on managing collections from ScanLoop, I needed to refactor collection apis into the service layer and add unit tests.

Removed ToUpper Normalization for new tags.

* Hooked up ability to auto generate collections from SeriesGroup metadata tag.
