Fixed running as service

This minor update will now allow a second instance, but it will not enable the folder watchers. It will also not update the history window unless you close/restart the app. The log tab will not display output from another running instances (such as a service). The log file has to be directly opened in order to see updates from the service.

If you need the UI to be fully functional with history updates, file watching, etc then simply stop the other running service/instance of aitool.exe first.
