7.x defaults and fixes

Two things here. 

One is adding default Creative Commons settings to the admin form, so that new objects start with your default. Otherwise you have to change them every time. Just saves a little effort.

Second is that the drupal_html_id('license_output') doesn't work reliably with AJAX. There is quite a bit of discussion about this on various forums. The form loads fine, make on change and AJAX works. But the second and subsequent did not seem to replace the license display.

I don't see why you would ever have multiple CC choosers on a single object, but if nothing else you may want to look at modify your code to just fix this one problem.

This needs to be removed so Travis will pass. Gotta love Drupal Coding Standards! :smile:
