kfet.open

kfet.open app
- Base data (raw_open, last_update...) is stored and shared through cache system.
- 2 websockets groups: one for team users, one for other users.
- UI is initialized and kept up-to-date with WS.
- raw_open and force_close can be updated with standard HTTP requests.
  At this time, there isn't any restriction on raw_open view. Common sense tell us
  to change this behavior.

Misc
- Clean channels routing.
- 'PermConsumerMixin': user who sent the message is available as argument in
connection_groups method, which returns groups to which the user should be
appended on websocket connection (and discarded on disconnection).
- New kfet.utils module: should be used for mixins, whatever is useful and not concerns
the kfet app.
- Clean JS dependencies.
