Added a couple of template validation procedures ("added a couple of templating system datatypes") to bring the kernel and templating system's view of datatypes closer together. Added to_sql/from_sql helpers to move that functionality from ad_form into the templating system.
Merged oacs-5-6 to HEAD. HEAD now installs and passes all core tests. There may still be some lingering problems due to my screwing up the oacs-5-6 branch earlier, I'll be looking into this later.
