Reorganized the project. Moved both the gazebo plugin and the controller to the Catkin build system.
Ajusted the collision geometry used by the VilmaCar model. Converted the controller to use Qt4 because Qt5 is not supported by ros libraries.
A .deb was created to install the plugin more easily, but it is not going to be supported anymore. Corrected the functions which were deprecated in the plugin using
https://github.com/yujinrobot/kobuki_desktop/commit/27e85fc224fc6198b55c5af0d066c7901af8ec0 fix.
 The slider used with the controller now correcly follows the steering wheel position, even when the car model is reset.
 Bug: model not reseting it's state when spawned or when the controller exists.
 The car center of gravity was also changed to a more accurate position using the car wheels weighting, but z position was taken as half the car height.
