* - Only show active devices in browse
- Refactor some stations APIs to return more info about what stations were added/updated and how many recordings were matched, if any.
- Simpler get APIs for retrieving group devices, group users.

* Revert docker files

* Fix stations tests

* Python formatting

* Adding missing apidoc info

* Fix comparison for retired stations in where clause.

* Fix viewAsSuperAdmin arg passing.

* Addressing review feedback

* Make bulk tagger deliver CPTV files instead of mp4 files.

* Fix query
