Unistalling Managment pack correctly.

I removed the custom action that stops the service and defined instead a "Control Operation" in Services page to stop it.

The advantage of the control operation is that it informs the OS that this will stop the service, so we don't get the "Files in use" dialog anymore".

All changes were done only the project of the merge module. Once you rebuild this one you can rebuild the other projects that include it too. 

I made tests only with the package that installs just Management Service and it seems to work.
