Ubercart

Hi. I was testing your 6.x version and found that it wasn't as flexible as I'd like it to be. I've attached an updated version here that makes the following changes:

• Move settings to checkout settings page instead of cart settings page.
• Place setting fieldset inside general checkout fieldset. This is to overcome the fact that the form elements have no weight and the uc_total_min form items were appearing below the submit button.
• Add a custom error message field.
• Change the names of the form variables so that they are easier to identify in the database and reduce the likelihood of naming conflicts.
• Add uc_total_min.install file with update function to change variable names for users with previous installs.
• Alter some of the name and description text on the forms for clarity.
• Re-work the the checkout validation to be simpler and to add the custom error message display. I also removed the || !variable_get('uc_checkout_enabled', TRUE) from the if statements because I couldn't see its purpose.
• Remove unused and commented out test code.

Cheers.
