QtService (Solutions for 4.x) needs further paramters...

It would be useful if it was possible to set a separate display name (parameter 2 in the call to CreateService on windows) and dependencies from other services (3rd last parameter in the call to CreateService, doubly \0-terminated unicode C-String) when using Qt Service.

It would also be handy if on Windows the service was allowed to increment the dw_checkpoint integer member for the service control manager structure while waiting to terminate as otherwise Windows can terminate the service hard (which could be too early for services where the deinitialisation can take longer than the preset waiting time of the SC-Manager).
