Fixes #27923 and #28000

Fixed a bug where the installer wouldn't grab current config if the salt
service was stopped
Added a switch to start the salt service at the end
Switch works with both silent and GUI installs
/start-service=1 will start the service
/start-service=0 will not start the service
Default is to start the service
