In build 10.0.2.46702, the SpellAlert key was changed from overlay to SpellActivationAlert and Masque was not updated to reflect this. This prevents any action button using the default API for spell alerts to not be updated correctly. However, Classic and some add-ons using third-part APIs still use the old key, so that needs to be accounted for, as well.
[x] Add support for the SpellActivationAlert key while retaining support for the overlay key.
