Title: freely positioned elements

This pull-request contains two distinct change sets:
1. Pulling the "canvas" apart from the "root" elements to make insertion of additional content into the root element easier. This can be used to put the fallback message or other control elements inside the root-div, making the markup cleaner.
2. Freely positioned elements: These elements are marked with the class "positioned" and will be positioned like steps, but do not show up in the steps list. They can be used to add additional content that is not tied into a single frame, e.g. a graph connecting several steps.
