Major update: changeover process is split into the core process and flexible, module-like hooks that can be freely configured to be executed before and after the changeover process; implemented the following hooks: logger, activity, storage, watches stop, watches start, delete folders, make folder; moved the redis database into a storage class; storage supports strings, lists and sets now; the storage template parameters in the source and target paths are jinja2 based now and allow the full jinja2 syntax; new storage event listener; if a redis value changes and the source or target paths use redis parameters the watch system is restarted; bug fixes in the REST interface; new storage REST endpoints; added error messages to the REST interface; simplified changeover REST interface; small performance improvement for the notification event handler
