Tidy up Phorum extension. Add svn:ignore, add img to the default list of allowed tags (for smileys), improve naming convention, move loading code out of main namespace, and add reset. Probably the last thing to do before this is feature complete is to have a WYSIWYG flag that turns on escaping for edit posts.
