Feature: Pair Categories (#35)

* Feature/pair categories re (#1)

Implemented pair categories:
- Paired users can now get tags
- Tags get rendered into the main UI as groups
- Tags are persistently stored on the local configuration

* Added multi-server capabilities and cleaned up code

- Tags and available tags are stored per API url
- Added a few tooltips

* Renamed both dictionary to reflect the fact that they are per-server dictionaries

* Swapped icons and no longer renders groups that are empty after filter
