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.
Hmm, actually I think there should be a break in the "AND" case as well, right after `matched = false;`
In both cases it just terminates the for loop so wouldn't affect the switch statement. Apparently labels are to be avoided as they are even more confusing https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/label
