Add version 1.0.3 to master branch

* Thrid functional release
* Switched from TCP to UDP (this doesn't use as much bandwidth and
multiple users can be "connected")
* Added admin user and guest user (config file has been updated
accordingly)
* Made Apache Commons Codec more lightweight (removed some of the unused
classes)
* Still insecure (password is being sent through packet as plain text
and is not hashed and compared until after it is sent to the server)
* Major optimizations
