Upgrade (breaking changes!)

With this upgrade we replace the widget that was used for the notifications. We use SweetAlert2 now. Inspired by the module that was already in the Marketplace by Jason Imeidopf. We have made it plug and play for nanoflows AND microflows. It will load the necessary javascript and CSS files. Only place the snippet in your layout and your are good to go. Exisiting calls to SF_CreateNotification are replaced by SUB_CreateNotifications. Rename the new microflow to the old name and back will solve this. The enums for status and position must be set again! It uses HTMLsnippet widget from the marketplace.
