* Delete the email related classes. They were an experiment but didn't work out.
* Change the way anchors are dealt with. Still need to finish some stuff in the MarkupDirector to create anchors with a name but no href.
* Move richtext.html into the tests directory.
* Create image tags in a better way, not adding width and height attributes where not needed.
* Better way of determining when to create a newline. Includes unit tests. There's still a qt-bug to workaround in the newline stuff.
* Move the MarkupDirector::Private class to separate files.
* Some style and indentation fixes to the Director stuff.
* Process block contents in an entirely different way to close and open tags in the correct order. Includes many unittests.

I know much of this should be in separate commits, but it's still in playground anyway...
