*If the addon fails to load, it is added to a list of failed addons. If you try to load the addon again without reloading the UI, you will not be notified of failure unless you use LoadAddOn and write your own edge case.
*As of patch 1.8, you can only use this for addons that are marked on demand in their .toc files (## LoadOnDemand: 1).
Functionally similar to this:
 local loaded, reason = LoadAddOn(name);
 if ( not loaded ) then
 message(format(ADDON_LOAD_FAILED, name, _G["ADDON_"..reason]));
 end
