GeoBlacklight Admin v0.3.0

This release marks the milestone of the Big Ten Academic Alliance running GeoBlacklight Admin in production. There are still issues to resolve, and I expect some underlying code shifts/refactoring, but the codebase is sound enough for use in our production setting.

What's Changed
