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...
