Correct initial issues discovered with Service Reconfigure

(1) Crash when determining whether to hide the reconfigure button for services
    created through automation w/o an associated service template.
(2) Service dialog lists and radio buttons showed the keys instead of the
    human-readable values.
Automate - add "finished" state to all provisioning and retirement
statemachines.

Created new /system/methods/statemachine_methods class, with new
 instances for each of the provision combinations and new method
statemachine_finished.
