Domain block (#76)
* start work on admin domain blocking * move stuff around + further work on domain blocks * move + restructure processor * prep work for deleting account * tidy * go fmt * formatting * domain blocking more work * check domain blocks way earlier on * progress on delete account * delete more stuff when an account is gone * and more... * domain blocky block block * get individual domain block, delete a block
