added ability to delete embedded posts (only the author and the person embedding can delete them) (this requires the embeds to be stored, they are deleted if the embed is deleted)

added filter to only handle reactions not done by the bot
introduced completable future to the delete message wrapper
fixed multi embed handling always resulting in two embeds
added logging of template exceptions
refactored link embed handling to be in a service instead of the listener
