Added a way to sort (with a prefix number) parameters in toolbox.
Can now switch between nearest neighbor strategies (kd-trees, k-means, linear).
Added parameters for all FLANN nearest neighbor approaches.
Added likelihood plot (including UPlot from UtiLite library and PdfPlot from RTAB-Map library).
Added general parameter "MirrorView".
Added general parameter "InvertedSearch" to create the vocabulary from objects descriptor instead of the scene descriptors. We can then compute likelihood of the current scene with all other objects (or another scenes).
Fixed a crash (in AddObjectDialog) when selecting outside the image.
Added OpenCV version used in AboutDialog.
