Log:
[NTOBJSHEX]
* Use lazy enumeration of the nt objects and registry keys, as intended for the
IEnumIDList interface.
* Display of the NT Object creation date has been lost in the process, but it was only
really used by symlinks.
* Symlink target display doesn't appear to work at the moment, will fix later.
