Comment 1 for bug 1400829

I've pushed a commit to the user/jeffdavis/lp1400829-flag-user-as-deleted branch of the working repo:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=commitdiff;h=5165881

This adds a new open-ils.actor.user.flag_as_deleted method, plus a new open-ils.actor.user.delete_card method for deleting cards, plus the requisite permissions for both. No changes are made to the user interface, so this is really just a first step, but it's useful to have the functionality as part of the Evergreen API. (Sitka has a custom web interface for batch patron deletion which relies on these new methods.)
