Minor schema inconsistency with property names for URLs

[iadgovuser1]

These are really minor, but I'm pointing them out for the sake of consistency:

• [project.]codeUrl versus [project.]downloadURL (e.g. Url versus URL)
• [project.]repository is a URL yet it doesn't have URL in its name
• [project.]license is a URL yet it doesn't have URL in its name
• [project.]homepage is a URL yet it doesn't have URL in its name

These are great comments. I'm new on the project and AFAIK, they were integrated into the new schema. Let us know if there's any other issues. Closing this now.
