HoloBam: Restart trebuchet on toggle change (1/2)

Allright, since everytime we enable the holobam mode, the icons of the apps involved doesn't change until a phone reboot or a trebuchet restart.
So we are going to call helpers that restart Trebuchet every time we toggle on/off the holobam toggle to update the holo icons
