"lock" Waivers after they are signed so they cannot be edited, and enable printing of waivers.

There is currently no way to "lock" a waiver after it has been signed. So after a volunteer signs a waiver, we (organization) can go in and modify the waiver verbiage, and still show that they signed it, dated, but with our new verbiage. This does not protect the end user, and unfortunately knowing that it can be modified, does not protect us as an organization.

We also need the ability to print the waiver once it has been signed.
