Fix DLL and driver versions unset when running ITMDRvr.exe -v

[aromanielloNTIA]

Resolves #17

This issue was caused because the call to the Version() function specified by the -v flag occurs before the DLL is loaded. This change loads the DLL up front, so that version information is populated before the call to Version().

I also changed the name of drvrVerDrvr to drvrVerPatch, to be consistent with semantic versioning major/minor/patch version numbers. I also added the drvrVerPatch to be printed in the -v message (it was already printed to the output file)

Example output:
