[kernel32]
- Modify reactos version APIs to report as a workstation instead of a server upon request. - Currently controlled via a system setting, cpl mod to follow. - Note: The kernel still reports as NtProductServer, as indeed it should. See issue #5003 for more details. svn path=/trunk/; revision=44483
