Last (?) of the changes needed for a working D7 version.  Fixed form handling in uc_product_power_tools.admin.inc, added admin settings form theme function, added dependency on the php module for use of php_eval() by Autogen SKU.

Initial port to Drupal 7.  Coder and Coder Upgrade fixes.  Some DBTNG changes.  Module will now install/disable/uninstall properly.  No guarantee all the functionality works...
