Add link to accept the EULA to the disclosure before submitting

I wanted to see if I could duplicate the link to accept the EULA and display it in the assignment disclosure so that it displayed to students before they submitted.

This would give them two opportunities to accept, one before and one after submission.

The styling is the same, but it may need to be made more prominent, which I think is on your to do list as well for the link in get_links().

I have tested this on our dev environment and it works for both JS and non-JS users.

Please review and let me know if I need to make any changes to it.
