Updated script added some security and readme features added $yourIP

Updated this script to add some security/input sanitizing for databases.
Added more documentation to the read me
Added $yourIP variable in config file so there is no need to edit other .php files than the main config

This is solely to help out new users without much security sense keep their databases more secure.
This version should not be considered secure, just less insecure.

Thanks for the good base Greedi
