FRCSim, Gazebo v7, and GearsBot example

[dpolito]

Looks like the current FRCSim package is setup for Gazebo v6, which is unavaliable for download. I just went through the setup instructions and have the same issue. Autonomous and Teleop do not work and I have the same error messages regarding libgazebo_physics.so.6.

I went through the exercise of linking the version 7 libraries to version 6 names, one by one to eliminate the error messages. The error messages go away, but eventually Gazebo stops running, no surprise.

Thanks for building a great tool. I will continue to try and track down the exact incompatiablity between v6 and v7.
