In AckisRecipeList.lua:
  Removed some garbage creation throughout the file by moving some table declarations and using twipe(). Made some code more readable by changing some if checks and using return.
In ARLFrame.lua:
  Removed empty-table creation from some upvalues, because their value is always set by addon:DisplayFrame() or InitializeFrame(). In addon:DisplayFrame(): Removed call to addon:SortMissingRecipes() because this is already done prior to calling addon:DisplayFrame().
