closes #313

To avoid some strange config sorting errors using the
DeferredImportSelector, switch to a real AutoConfiguration activated by
a marker bean

This adds a new FilteringNotifier which can use filters to suppres certain
events from being notified of. Two filter implementation are provided, one
filtering by name and one by id. Additional when a FilteringNotifier bean is
present, the autoconfiguration creates a REST-controller to add and remove
filters at runtime.

The RemindingNotifier sends periodic notifications using a delegate. It must be
added explicitly to the ApplicationContext

 * Use @EventListener instead of ApplicationListener-interface
 * Don't inherit ClientApplicationEvent from ApplicationEvent - so JournaledEvent isn't needed anymore
 * added eclipse formatter rules
 * reformatted all files

Added a simple event journal, jorunaling all ClientApplicationEvents using a simple, non-persistent store. So all information is lost after restart. Added corresponding view to UI.

* make sure non-UP applications are shown at the top of the list  (closes #55)
* refinements for health-section
* remove-button for all apps
* fixed headers in details view

using Gulp & Browserify
with a little help from https://blog.codecentric.de/en/2014/08/angularjs-browserify

* Separate AppStore from AppRegistry
* Allow Id generation to be altered
* Remove logic from Application; Move id genretation into AppRegistry
* Make AppStore threadSafe
