[enhancement]: support clearing query and http cache (#475)

* [enhancement]: support clearing query and http cache

  - Adds the ability to invalidate all queries (useful for forcing refresh, and clearing lyrics which are cached forever)
  - [Desktop only] adds the ability to clear the Electron HTTP cache (e.g. cached images)

* use clearer language

* move cache settings to general
