Show if page has programming/script rights under Information tab for advanced users

Right now, to find out if a page is saved with programming rights, you have to:
a) As admin, go to the wiki preferences > rights management and see if the user that last saved the page has programming rights
b) As a normal user, write some velocity code to ask if the user that last saved the page has programming rights

Also, it's very easy to save the page with another user and lose programming rights without knowing.

The suggested improvement involves adding an extra section under a page's Information tab that says if the page is saved with programming rights or not. Also, this section could be made available only to advanced users which are the main target.

This is just a minor UI improvement that can help a lot.
