Initial commit of uc_product_power_tools module. Product Power Tools gives ubercart store admins the ability to disable, or preset and hide virtually every product specific field for product class nodes. This is useful when you have product classes that do not require all of the possible product fields; especially if less computer savvy people will be dealing with data entry of products for sale on the site.
