Adirelle:
    - Added a "Debug macro" panel for debug versions.
    Conflicts:
        Config.lua
    - Special case for Treant form, which is detected like a form but cancelled like an aura...
    - 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.
