-Added parameter "Mem/ReduceGraph" with new link type (NeighborMerged)
-DatabaseViewer: add Info panel, fixed empty extracted database when "RGB images" is not checked
-ConsoleWidget: added buffer size and refresh rate options
-DBDriver: new database info getters
-Graph: added reduceGraph() method, added Dijsktra computePath() with links only
-Updated default parameters: RGBD/LocalLoopDetectionSpace=true, RGBD/LinearUpdate=0.1 and RGBD/AngularUpdate=0.1
-Goals are saved with label instead of ID if the target node has a label
-DataRecorder: fixed saving incrementally the database (instead of only at the end)
-MainWindow: When waypoints are used, resend the current goal (1 sec delay) if it has failed setting it
