Create Session Tokens with ZwCreateToken

[iamacarpet]

As a starting point to implementing RunAs functionality, we'll need to be able to create tokens with ZwCreateToken

This is an apparently undocumented API that allows you to execute as a user without their full credentials.

This library normally runs (for us) as NT AUTH\SYSTEM, so permissions shouldn't be a problem.

A good example, I'm told, is "RunAsEx" on CodeProject.

This will then allow "CreateProcessAsUser" with that token.
