Mostly removes creation of throwaway objects from chameleon items

- Replaces the creation of throwaway items from New() with initial() calls for all chameleon items.
- Unfortunately throwaway items could not be removed when switch appearance, as initial() does not work very will with list vars.
- Makes chameleon item name cache lists global.
- Makes chameleon guns a subtype of energy guns, removes chameleon magazines.
- Moves chameleon.dm to clothing module root
- Items without icon or icon_state are no longer selectable as chameleon appearances.
- Chameleon verbs go in their own panel.
