Freeze modules with hard coded http krefs

[HebaruSan]

I was starting to look into finding the correct denominator for the frequency number in KSP-CKAN/CKAN#3571, and I noticed these two mods with http krefs containing hard coded URLs on GitHub, one from an invisible release that somehow is still downloadable, and the other just a random ZIP committed to a repo. Both look quite abandoned, but they will never be auto-frozen by the AutoFreezer because the http kref does not support release_date

• https://github.com/SpaceShipShipYardEnterprises/SpaceDock (last update Nov 2016)

Now they're frozen.
