To avoid confusion, the unused SET_CIRC_MISSING permission should be removed.

Okay, signoff branch here: http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/csharp/lp1498155-remove-set_circ_missing_perm_signoff

I added a commit that also deletes any rows in permission.usr_perm_map since I can see that perm has been granted to individual users in PINES.

Pushed to master. Thanks, Josh and Chris!

I decided to not backport this as it's just tidying things up, but I won't object to anybody else backporting it.
