Also display configuration file (torrc) location when running as Windows service

When normal running TOR on Windows, it prompts the reading configuration file location such as

Dec 23 05:31:11.523 [notice] Read configuration file "C:\Users\<USERNAME>\AppData\Roaming\tor\torrc".

But TOR does not prompt this location when running as Windows Service, and the torrc file is usually in a totally different location when running as service. TOR just prompt this service is started in command line.

D:\tor>tor --service start

Service started successfully

so it is hard to find which torrc file it is reading. Need a fix on this issue to make it a litter easier.
