Adjust program detail page URL routing

The new URL pattern expects a program ID and allows a program name to be included, if desired. It will match paths like 'programs/123/' and 'programs/123/foo/', but not 'programs/123/foo/bar/'. The given ID is passed to the view, where it will be used to retrieve program data. Part of ECOM-4415.
