Playing around with ogre 1.8 and 1.9.

[NikolausDemmel]

• For now they live in separate formula, but only for testing.
• Eventually if ogre and rviz work with 1.9, we should update the
  ogre formula to 1.9 (and maybe keep versioned formulae areound)
• The 1.8 formula builds on Mavericks, but since 1.8 did not really
  support libc++ and I more or less blindly backported some patches
  from 1.9 to make it compile, I am pretty sure that there are runtime
  issues. Focus should be on 1.9
• It seems that gazebo 2 is working with the 1.9 formula, devel variant, so best try out brew install ogre1.9 --devel.

This PR is more for testing out the updated formulae. I don't expect
it to get merged. See comments above.

Hey all, I'm having an issue installing 1.8 on osx 10.11.3 (el capitan)

How can I get around this?

[scpeters]

we have merged an ogre1.9 formula in #172 so I think this can be closed

[NikolausDemmel]

Sure. Thanks for cleaning up.
