Rake task for changing the state of a Form

[chao-xian]

What problem does this pull request solve?

We have some forms that were fiddled with in the database to remove them from service. This was prior to having the Archive functionality we now have. As a consequence some of our metrics data is counting wrong.

Example:

XL Bully - the "live" version was deleted, but as it was once live it should be counted as being published some time ago.

This PR adds a method and accompanying rake task for switching a Form's state programatically, in the shortest number of steps.

In the case of XL Bully it would make it live and then immediately archive it. As it's done programatically, it would be much quicker than one of the admins clicking around to do the same thing. It also decreases the likelihood of a user finding the live form.
