Reusing the Amaya general mechanisms for setting namespaces and charsets on the annotation body. New annotations will use the utf-8 charset by default. If we saved such a document, this resulted in a duplication of the HTML elements. Make selection work on the desc item, rather than on the thread item.
Some bug fixes.
Now showing the title of the annotations in the thread. Reduced the thread indentation. Some bug fixes too. Window guys, don't forget to recompile the schemas. Early commit of the annotation thread code.
