Organizational Changes and Linux Support

There are a lot of small changes in here, but very few code changes.
- moved dylibs to other folder
- re-registered dylibs using install_name_tool
- NiTE data files are now in $project_dir/bin/data/NiTE2
- Drivers and now in $project_dir/bin/Drivers
- added addon_config.mk

- added .so files for linux
- changed a few openni and nite .h files (changed Status enum to Status_)
    it was causing a compile error.
- Put libNiTE2.so and libOpenNI2.so in bin/libs/

I have not updated the examples. I will when I have more time.
Be sure to test the examples in OSX.
