Form validation and form_validation.php

@skunkbad
That is a really good idea. On a recent site I decided to be really strict with myself and started putting all the validation rules into the normal form_validation config file. It soon became so huge I was worried that loading the entire array just to get a couple of elements was starting to be an issue, so put all the validation rules back into the libraries.

However, doing as you suggest here is a great idea. Will try it out. Thank you.
