- Our NtCreateKey currently allows building trees (which is incorrect) if the parent key is a symbolic link (which does exist), but if the target doesn't exist (Since the check 'does parent exist' is done Before the symlink is converted to its target. One side-effect is that although we create the CurrentControlSet symlink to ControlSet001, we never create ControlSet001. We end up creating it later during the boot by creating a sub-key, by exposing the bug in NtCreateKey. Since the new NtCreateKey uses the new parse routine code and doesn't exhibit this bug, we have to create ControlSet001 manually to avoid a failure. Other bugs of this nature may exist. Bug found and fixed by Alex.

- Implement the last bit of the new parse routine (creating children) and write a new version of NtCreateKey which uses the parse routine. Disable it for now until other latent bugs are fixed.
