Changes mime abilities into spells

 - Admins can now give the mime abilities from the 'give spell' menu. Unlike previous mime abilities, these are not transferred when a mime is cloned. (Fixes #1376)

- code/game/jobs/jobprocs.dm is unused. Waiting for opinions if it should be removed, kept, or moved to unused folder before I touch it.

- mind.special_verbs is now completely unused. Someone might want to remove it or find a use for it.
