Ch 1357 - Add a new agent type for fixed targeting to Acquia Lift module

For now the agent type will only show up if you have the acquia_lift_target_enabled variable set to 1.
Does this not cause any problems with the fact that you are breaking out of a loop within a switch?  I was going to comment that you should "break" out in the "AND" case above, but figured you kept it running for simplicity.  I know you can do both with labels, but I don't see that hear.  Of course then again... if it works, it works... but it looks a bit odd.
