Ez sql 3.0

Hi Justin,

I've done a lot of work on ezSQL to bring it up to PHP5.2+

That included extending some escape functions, standard formatting, unit tests, PHPDoc tags, and the PHPDoc documentations.

The code will be used in the ongoing development of MODX Evolution. It has to fit the standards there, which meant PHPDoc and unit tests.

Maybe this might be helpful for others.

Best regards and happy easter
