Fixes a problem where uc_ajax_cart_preprocess_uc_ajax_cart_block_content()
could end prematurely if no discounts were in place, causing $items to be
stdClass objects instead of arrays in the theme template.

Add clicked_button class tu submit button to allow uc_out_of_stock to perform
its validations.

ajaxCartUpdateCartView calls ajaxCartFormSubmitted, and then ajaxCartReloadCartView, but ajaxCartReloadCartView is called at the end of ajaxCartFormSubmitted, so ajaxCartReloadCartView is called twice and consecutively. So, removing ajaxCartReloadCartView from ajaxCartUpdateCartView makes it the same as ajaxCartFormSubmitted, so ajaxCartUpdateCartView is removed and substituted by ajaxCartFormSubmitted.

(no, is not a tongue twister, actually is a serious commit message ;-)

Added desc field to show attribute info for product.

Issue #897038 by tunic: Fixed duplicate remove message with new Ubercart's cart page remove buttons.

Added option to force cart reload on page load with registered users.

Remove form cart message on completion are never displayed. There's no reason to show them.

Minor changes to meet Drupal coding standars.

Thanks to LG666 to pointing it out.

Ubercart dev uses remove buttons instead checkboxes in cart page. Added code to
use both solutions. Thanks to rei and emattias to pointing out this bug.

Added preprocess block function to use user supplied cart title using standard drupal block settings.

Check if there're any attributes when checking product stock.
