catkinize

Hi, uvc_cam is great, and I want to use it catkin based environment.
If you want to do catkinize it, you can use this patch.

- update package.xml and CMakeLists.xml by catkinize script
- update UVCCam.cfg (use dynamic_reconfigure.parameter_generator_catkin)
- package.xml's maintainer is ogura for now. Please change it.
