6.x

#1920748 by thedavidmeister, fix functionality when site_404 and site_403 variables are not set.

Complete rewrite of the 6.x-1.x version of the module to work with Drupal 6 and Ubercart 2 and to support the XML API of SOFORT AG instead of the classic API.

• Multiple changes to the widgets HTML. Make sure to check the widget and sidebar look before upgrading production websites.
• No more Libraries API dependency. All external libraries are downloaded from the CDN. It's safe to remove easyXDM from you website if it's not used by other modules or the website at all.
• Editor implemented on the CMS side instead of popup window from the Contextly server.
• Add support for TinyMCE starting from 3.4 up to the latest 3.5.x. The 4.x branch is not supported yet.
• Add support for CKEditor 4.x, tested up to 4.2

Please don't install or upgrade to this version, use a later one. Released for historical reasons only.

• Revised _create_workflow_state_for_node to mirror behavior of Workflow module workflow_execute_transition function. This includes calling all module hooks, transition events, and cleanup of any scheduled transitions for the node.
• Greatly expanded the cleanup function to address issues that are not cleanable within the stock Workflow module. Now performs a purge of all orphaned entries across all workflow tables, and removes all workflow states marked for deletion.

Fix undefined offset error.
