Adirelle:
	- Restore favorite on load, then only on the first typeless COMPANION_UPDATE event.
	- Slightly simplified the concatenation of macro parts.
	- Hopefully fixed GH-10.
	- Do no try to simplify the conditionned mount casts.
	- Force favorite restoration on Blizzard_PetJournal load.
	- Propose to cancel priests' Shadowform.
	- Do not erroneously cancel form.
	Should fix GH-11.
