Add a list of projects to generate, verses simply versioned

Without this PR, every addition to versions.yml `current` block generates directories and assumes they are documented projects. This doesn't make sense in secondary projects like Stanchion.

This also contains the 1.4.4 CS generated download data, and a minor patch to displaying Reference icon (which really should be fixed to use classes, not title names @barrettcox80. global_nav allows for custom css `class` names)
