Add filter on type of license about open-ledger HOT 6 CLOSED

Here are the guidelines we provide platforms: https://creativecommons.org/platform/toolkit/#enabling-cc-search-and-discovery

We prefer by category of reuse (eg. stuff I can remix commercially, versus license).

from open-ledger.

Note that a very literal implementation of this will mean that a search for CC-BY will not return anything from Rijksmuseum or Wikimedia, as those are CC0 only.

OK, I updated the prototype to include the two recommended categories from the guidelines.

You can also request specific licenses if you edit the URL (see the "sheep" option in the "Searches to try" list). We could bury that in an "advanced search" option.

LICENSE_GROUPS = {
    # All open licenses
    "ALL": ('BY', 'BY-NC', 'BY-ND', 'BY-SA', 'BY-NC-ND', 'BY-NC-SA', 'PDM', 'CC0'),
    # All CC licenses
    "ALL-CC": ('BY', 'BY-NC', 'BY-ND', 'BY-SA', 'BY-NC-ND', 'BY-NC-SA'),
    # All licenses allowing commercial use
    "ALL-$": ('BY', 'BY-SA', 'BY-ND', 'CC0', 'PDM'),
    # All licenses allowing modifications
    "ALL-MOD": ('BY', 'BY-SA', 'BY-NC', 'BY-NC-SA', 'CC0', 'PDM'),
}

I defined the above as special groups of licenses we may want to treat as a unit. Let me know if you can think of other categories that would be useful.

These filters look good to me for now, though the actual search returning them seems broken, but I'm sure you're working on that!

A search for "sunset" with "Use for commercial purposes" and "Modify, adapt, or build upon" both checked should not return NC or ND results.

I believe this should be fixed.
