AriesParts: Support for BLN settings

This commit adds a new tabview to allow the management of BLN features.
It's now possible to set:
- the way a notification will be reported by touchkey lights
  (disabled, blinking lights, static lights, blinking and static lights)
- the duration time of blinking lights
- the duration interval of each on/off blink
- the duration time of static lights

The chosen settings are automatically restored after a reboot.
