uc_ajax_cart 6.x-2.2

This release is a primarily bugfix release. It resolves issues blocking the 6.x-2.2 blocker tag.

Note: Issue 1881758 is currently being investigated, 6.x-2.2 may have broken the cart contents block for anonymous users when caching is enabled.

Issues resolved:

• #1429944: Duplicate message when remove item from cart
• #1481182: possible to add noscript link if javascript is disabled?
• #837176: Less Intrusive Status Update for Customer
• #1493398: Hitting Enter when changing a quantity resubmits the form and can lead to further issues
• #1637656: Use AJAX cart/Add to Cart buttons only when viewing website on mobile device?
• #1664188: Invalid argument in foreach in uc_cart.module on line 1614 on /uc_ajax_cart/update
• #1635010: Call undefined uc_product_get_attributes() method in uc_ajax_cart_add_to_cart()

A patch from hanoii also caused some restructuring in the module to make the popup messages generated by JavaScript more themeable using Drupal.theme(). The refactoring also resolves #1778548: Popup message simply says "cart"... customers assume something is broken.
