* New rtabmap-reduceGraph CLI tool
* fixed some edge cases
* Regenerating optimized map if there was one before reducing the graph
* addMoreLoopClosures: refactored how ctrl-c is handled to stop faster when no loop closures are added
* Added kilted status
* Make offline tool always propagate neighbor merged links
* removed a parameter
* fixed disconnected graph
* fixed --help
* Added error log on Kp/NNStrategy not compatible with huge vocabulary. ReduceGraph/DetectMoreLoopClosures: Make sure original parameters are saved back on closing. g2o: fixing optimizer to Levenberg for SBA to avoid [SetJac] infinite jac fatal error.
* exposing neighbor merged ratio parameter to the tool
* show param in log
* refactored detectMoreLoopClosures to ignore too close nodes in terms of neighbor links based on Mem/STMSize parameter. Reduce graph: added direction parameter.
* Simplified: removed ratio parameter, removed recursive reduction. Just don't reduce if a NM link is longer than maxDistance.
* Removed NNStrategy override, as it was still done on closing when we changed back to original params
* DBViewer: show missing links when showing OptimizedPoses in GraphView, fixed clicking on landmark links
* DetectMoreLoopClosures: Added support for min graph distance option in MainWindow and DbViewer
* slight renaming of ROS jobs
* reprocess: added option --params_last
