Add 'Run SMC file' button to Service Manager Dialog (GUI)

    When the Service Manager starts, it runs the commands in the SMC file. However, once it is running, this file is not used again. It would be convenient if the Server Manager Dialog program had a 'Run SMC file' button that would run the SMC file anew. This would make it easy to start up the Automation Engine, for example, without stopping and re-starting the whole Service Manager, and without having to start each AE server process individually.
