API Changes
---------------
* Add setCurrentQuery() method on FilterController
* Important change how modules save/load data into project files. The WorkspacePersistenceProvider interface from ProjectAPI now uses StAX instead of DOM. The writeXML() method now uses XMLStreamWriter and readXML() XMLStreamReader. Backward compatibility can't be assured, modules have to use switch to StAX.
* Added support of shortcut keys, availability of items and sub-items creation to Data Laboratory context menu actions (NodesManipulator and EdgesManipulator). Also now Visualization API has an SPI for adding context menu actions (GraphContextMenuItem) to nodes like DataLaboratory does with NodesManipulator. Note that they share the interface ContextMenuItemManipulator from Data Laboratory API, so they are compatible, being able to reuse actions on nodes for Overview and Data Laboratory.
* Add removeMetaEdge(Edge) to manually remove meta edges. Add getTotalEdgeCount() method to globally count the number of edges, regardless if the edge is proper or meta.
* Add methods in Graph API to better combine edges and meta edges features. Add getEdgesAndMetaEdges(Node) and getTotalDegree(Node) methods, as well as their in and out variants for HierarchicalDirectedGraph.
