introduced eh-cache as a caching provider instead of caffeine to be used in hibernate (only ram cache is currently possible)

added caching configuration for 2nd level caching in hibernate
added command to clear hibernate caches
changed some interfaces so the api looks a bit more consistent (return the created/updated value)
split user management and user in server management
added try catch block to message received listener execution, to make them independent
moved some feature flag methods to the feature flag service bean instead of the management service, as they used the FeatureEnum directly
fixed feature disable text always rendering
removed some non embed logging
fixed message embed template
added exception logging to message embedding
