getBreakfast is a boolean that says whether we do "breakfast" upon login
breakfastAlways is a string that is a list of skills that are part of breakfast, whether in Hardcore or Softcore (as opposed to breakfastHardcore and breakfastSoftcore, which are also lists of skills).
"alwaysGetBreakfast" is not part of KoLmafia itself. Perhaps you have a script which uses it?
