create easy user setup in both systems

[kvimber]

• system needs a good way to create a user, and enter their information to the pass.txt file
• needs to hook up with mc_security's build_user_line function, which puts together the correct pass.txt file line format given the user's user name and password

[kvimber]

• written a command line tool now that will ask the user for their username and password, and add the hash to the pass file
• can run this by running the mc_security module
• this will work on both systems, but will work like running a cli module
• should test out on windows to see if it opens a command line window. If so then that's alright behavior for this

tested this in windows, everything works correctly, so I'm closing this.
