Updated following fields so that they do not pack data into data_content.content, but use data_content.content, data_content.content1, etc: - URL field - File field - Picture field Note that above changes to the way data is stored means that the new implementation is not compatible with previous version. Updated textarea field. Added relevant help messages. Added richtext editor support. Removed ability to restrict allowed formats for the textarea field. Misc bug fixes and display tweaks.
