Added Basic Login Script

Added a simple Registration/Login script that creates a %userid%.ini
file to store all data on a user.
So far the only data stored is Cash, Deaths, Kills, Password and Admin
status.

The pass is stored as a Hashed string for security reason.

Notes: Does not store player Location. Does not store player Health.
Does not have a valid player spawning system.

Next: Script will store player location. Simple spawning system will be
added.
