reworked exception handling, different exceptions whether or why it failed, all of which are unchecked

added feature flags for commands/listeners
added enable/disable command
added feature flag handling to command received handler
added boolean parameter support
fixed 1 parameter commands
fixed posttargets not working on multiple servers, removed unique constraint on posttarget names
added setup validation to suggestions
added quartz property loader
moved join/leave logger to moderation
reworked the way the message listener are handled (separate listener around)
