* The /datum/category_item/player_setup_item datums did a good job of organizing the code for loading/saving/editing preferences data, but all of the code that applies preferences to newly created player mobs was still in a single function.
* This change adds a new proc to player_setup_item datums: copy_to_mob() which is called from the traditional copy_to() proc, allowing each preferences datum to apply its own character data to the mob.
* This allowes new preferences to easily compartmentalize their new code.
* I also moved all the code for existing preferences from copy_to() into the copy_to_mob() on their respective preferences datums.
