Minor Vandervecken fixups

There have been several reported minor issues with the new build scripts. This pull request addresses those reported to date, but is by no means comprehensive.

### General
- Rearrange a few includes/dependencies
- Modify references to link back to this repository
- Migrate NOX10 and Ryu RFProxy implementations to this GitHub organisation

### OVS
- For manual build from source/git, update to install via new upstream scripts
- Default to 1.10.0 for installs prior to Ubuntu 12.04, or when Ryu-RFProxy is requested

### Ryu-RFProxy
- Add missing dependencies
- Ensure that version 2.0 of the controller platform is installed, not newer, not older
