As a commons user, I want to be able to filter my search results by license type so that I can select images that I can use.
Acceptance Criteria:
[] A "license" filter is added that allows users to only see results that have a certain license type.
[] The license filter should only appear on the Images, Audio, and Video tabs.
[] The license filter should have the following options:
[] "Use with attribution" - this is everything with the CC-BY license
[] "Use with attribution and same license" - this is everything with the CC BY-SA license
[] "No restrictions" - this is everything that's either CC0 or in the public domain
[] "Other" - everything else
[] The license filter should use only license data contained in structured data statements
[] The license filter should behave and look like the "media size" filter:
