Contribute CKAN Code back to upstream projects following 1.5 Release

[mwengren]

Not sure how far down this road we've gone with some of the capabilities and UI controls we've enabled for our own Catalog, but in order to close the loop and contribute back to the CKAN community, let's spend some time to engage CKAN developers and see if we can get some PRs accepted (or at least submitted) to contribute back these enhancements to the core.

Maybe each needs to be separated into a distinct extension? We can discuss how to proceed once the release is out.

Some functionality examples to consider contributing:

• Time Query Control
• Schema.org enhancements
• CF/ACDD display and query/filter functionality
• Depth query
