Comment (by TimothyBlynJacobs):

 I made a couple of changes.

 1. Metadata has subtypes now, so we need to take this into account when
 sanitizing.
 2. We weren't handling the slashing of meta key consistently. It needs to
 be slashed when updating meta, but unslashed for all the other functions.
 Because of this I changed the code to keep the unslashed versions around
 instead of continually unslashing them and then slashed as the values went
 into `update_metadata()`.
