Adds new console command, 'note', and modifies suspend console command to check for notes before running the suspension. Will allow antispam team to note accounts that are frequently reported for spam but are actually legit usage, to prevent having to keep lists or constantly tell new antispam team members 'no, we checked that, it's legit'.
Make error message more explicit. (Realized while demo'ing that it needed more cowbell.)
Remove unused declarations, change from set_prop to clear_prop
