hector_quadrotor_gazebo/hector_quadrotor_pose_estimation: added parameter file for hector_quadrotor_pose_estimation for a simulated quadrotor

The parameter file disables the auto_elevation, auto_reference, auto_heading modes of hector_pose_estimation and sets the corresponding values
manually with what is simulated in the gazebo sensor plugins. This simplifies the comparison of estimated poses with ground truth information.
hector_quadrotor_pose_estimation/hector_quadrotor_gazebo: updated package for the latest version of hector_pose_estimation

* Geographic reference latitude and longitude set to 49.860246N 8.687077E (Lichtwiese).
* Reenabled auto_elevation, auto_reference and auto_heading parameters for hector_pose_estimation.
  hector_pose_estimation will publish the world->nav transform depending on its reference pose.
