Contsants - Add Windows Username

[matthewbechard]

It would be helpful if the Constant engine type included just the windows username thats logged in.  The username is already in the two paths(tempfilepath and workflowdirectory), but I need just the username alone. Having it as a user constant is not not quite what I was trying to accomplish.  I wanted this to be dynamic.
