added configurable warning and success reactions

changed that channels dont actually get deleted, but rather with a deleted flag, so the foreign keys are valid
added more optionals to server/channel/message/member retrieval
added throwing exceptions instead of just returning null
fixed filtering of deleted channels while the bot was offline
fixed channel listener
added message deleted listener structure
moved quartz properties to general application properties, because they were not found in the separate one
added try catch to reminderJob, so that the job is not in an invalid state
we now completely remove the starboard post, in case it falls under the threshold
added code to 'ignore' a staroard post form further stars, in case the post in the starboard gets deleted
now actually setting the reminded flag on a reminder
added handnling in case the channel to remind in does not exist anymore
