Auto Update in 1 line of code

This module will download a referance file (included, see usage) and check the values from that against current ones. It will then ask the user if they wish to see information on the Update and then if they wish to download it. If 'yes' then an file is downloaded off the Internet (should be a Self Extracting Zip/EXE for ease of use). Please leave a quick comment and rate this so I can make better versions.
