Languages for the cloned!

Currently, clones have no languages, which can be problematic for reasons.  This fixes that.  The language list is saved within the cloning record, then that list is applied to the new mob. Tested with both the mrace language and secondary languages and cloning from a backup.

... I'm not entirely certain why cloning from a backup has an extra thing passed to growclone(), but I'm sure everything would implode if I had deleted it.
