Ethan Centaurai:
	- Appearance: Check for new buttons on ADDON_LOADED events instead of every second.
	- Appearance: Set the default minimap strata to LOW.
	This matches Blizzard's default minimap strata settings.
	- Appearance: Simplify the strata options to low, medium and high.
	- Appearance: Remove debug.
	- Appearance: Fix button border alpha feature.
	Why this was not throwing up errors is beyond me.
