Adds DMagicOrbitalScience

If @DMagic1 is okay with it, I'd like to add DMagic Orbital Science to the CKAN.

A warning, though: when I tried using the vref to get the version info from the .version file, netkan encountered an error: "Bad embedded KSP-AVC file". I don't know what's causing that, but if we skip avc support, the mod installs just fine.
