Title: OpenSceneGraph 3.0.1 and Collada

The first two commits belong to a [previous](https://github.com/mxcl/homebrew/pull/5965) pull request from @rpavlik. For some reason that pull request was never closed.
The latest commit is just my update the previous openscenegraph formula from 2.8.5 to 3.0.1.
