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.
