* add more stringent checks for remote status permissibility * add check for inreplyto of a remote status being a boost * do not permit inReplyTo boost wrapper statuses * change comment wording * fix calls to NewFederator() * add code comments for NotPermitted() and SetNotPermitted() * improve comment * check that existing != nil before attempting delete * ensure replying account isn't suspended * use a debug log instead of info. check for boost using ID * shorten log string length. make info level * add note that replying to boost wrapper status shouldn't be able to happen anyways * update to use onFail() function
