Removed old smach-based behaviours
[ranger_monitor] Tuning interface
Mark as invalid RaB readings out of certain bounds
Scale value is now provided by the main node

While here:
- reset the odometry when docked on the charging station
[nav] Hopefully fixed 'turn'

Not tested though
[nav] Added easing to move
Fixed more issues with beacons localization

- correctly compute and use the beacon *orientation* (instead of the angle the beacon is seen at)
- be conservative with beacons reading validity: must be facing the robot to be considered as valid
Compute, store and use last valid beacons' position
[nav] Minor tuning
[nav] Should fix a bug when summing total rotation in turn
Log aseba events in a separate logger

...so that they can be disabled if needed
Update croquignole_baseline to current API
