data: fixes and improvements

* save forward declarations of classes and structs as NODE_UNDEFINED_TYPE
* put whole files on top in snippet sorting
* uses aggregation count as weight in graph layouting instead of adding all edges to graph
* refreshing all views of components on MessageRefresh in ComponentManager
* reloading ApplikatinoSettings on MessageRefresh
