Some more Mi Band pairing improvements #180 

- listen to notifications early -- the band then actually tells us that
  authentication is required
- check for this after sending user info
- add authentication states to GBDevice
- workaround for event problems in pairing activity (delivered although
  already unregistered)
- BtLEQueue now deals with gatt events coming *before* connectGatt()
  actually returned (namely the connection event)

###Changelog
####Version (next)
* Pebble: Support Pebble Health: steps/activity data are stored correctly. Sleep time is considered as light sleep. Deep sleep is discarded. The pebble will send data where it deems appropriate, there is no action to perform on the watch for this to happen.
* Pebble: Support Pebble Health: steps/activity data are stored correctly. Sleep time is considered as light sleep. Deep sleep is discarded. The pebble will send data where it deems appropriate, there is no action to perform on the watch for this to happen.* Mi Band: improvements to pairing
####Version 0.7.4
* Refactored the settings activity: User details are now generic instead of miband specific. Old settings are preserved.
