Bump version to 0.0.3: change Fortitude::Widget#to_html to not require a RenderingContext, and to return the resulting HTML; #render_to now (for performance reasons) is the "old" #to_html, which required an explicit RenderingContext and returns whatever the widget's #content method returns. This should make using Fortitude without any framework at all (neither Rails nor Tilt) considerably easier.
