[Servman] Make the property sheets modeless so users can open multiple services at the same time (#166)

[SERVMAN]
    - Make the property sheets modeless so users can open multiple services at the same time
    - Untested in ros. In fact we have no code or tests cases to check that modeless property sheets work, so please raise a bug if you find any issues with the app.
    - Dedicated to reactosfanboy
