Ability to enable/disable Litespeed (lsapi) from PHP Selector

[chrismfz]

Assuming that litespeed is installed, and this is permitted by admin / ACL / configuration options: It would be nice if the customer himself could enable / disable litespeed and switch from suPHP to litespeed from inside PHP Selector. A work load would be reduced (tickets informing to switch to litespeed for testing, or switch it back etc) and it should be better as a service.
