New issue 1219: Shader files are not installed correctly https://bitbucket.org/yt_analysis/yt/issues/1219/shader-files-are-not-installed-correctly

Kacper Kowalik:

As reported by @a_gilbert

``` copying yt/visualization/volume_rendering/shaders/default.vertexshader -> build/bdist.linux-x86_64/egg warning: install_data: setup script did not provide a directory for ‘yt/visualization/volume_rendering/shaders/passthrough.vertexshader’ — installing right in ‘build/bdist.linux-x86_64/egg’ ```

shaders are installed into the main egg directory instead of `yt/visualization/volume_rendering/shaders`
