explicitly requires "cv_bridge" package

[dbcesar]

Hi,

The file "gazebo_ros_image_sonar.cpp", in package uuv_sensor_ros_plugins, includes "cv_bridge/cv_bridge.h".

This commit fixes the following error: uuv_simulator/uuv_sensor_plugins/uuv_sensor_ros_plugins/src/gazebo_ros_image_sonar.cpp:50:33: fatal error: cv_bridge/cv_bridge.h: No such file or directory

I have compiled cv_bridge from source, from the following repository: https://github.com/ros-perception/vision_opencv.git. I'm not sure why it didn't pop up before.

@dbcesar Sorry for the late answer, but could you, please assign the commit? It's a requisite of the project. This will do it git rebase HEAD~1 --signoff
