CKAN integration

[sumghai]

The Comprehensive Kerbal Archive Network (CKAN) is a metadata respository and associated tools to allow users to find, install, and manage mods for Kerbal Space Program. It provides strong assurances that mods are installed in the way prescribed by their metadata files, for the correct version of Kerbal Space Program, alongside their dependencies, and without any conflicting mods.

I'll need to talk to one of the CKAN guys (probably @pjf) to what info I need to provide to get a metadata entry for SDHI SMS submitted - particularly the various dependencies which may or may not be listed under CKAN themselves.

CKAN integration has been implemented and tested successfully for the main add-on and its dependencies.
