Issue: Enforce Branding Expiration

According to the License Agreement, it's currently up to the customer to re-apply the branding when their removal rights expire. However, most users probably don't know about this rule and probably wouldn't be aware enough or have the time at the actual expiration to make the proper changes. Thus, this invites a handful of people to unintentionally violate the Agreement. This also diminishes the value of branding removal services that other users have paid for properly.

Instead, VaultWiki should be internally aware of add-on expirations like this, and automatically revert to the default behavior when it passes.

Fixed in the next release. This does not make it any easier or harder for users to violate the agreement by manually removing the license text.
