#16 Start window is centered over dual screens

[Heiko Tietze]

Please use the default position of forms so that the OS can decide where to place it. Alternatively you should use primary/main screen center (which might be wrong in some situations) because the current position centered over the whole width doesn't takes dual screen layouts into account.
Great sports tracker, by the way!
