 *  Brute force tidy up after CVS server crash: this time it should work.

 *  Major changes, primarily to htform: the action despatcher has now
 *  been built in Form, supported by a new class ActionWidget. This of
 *  course has required changes in classes built on Form, and
 *  particularly in AuthenticatedForm and TableWrapperForm, which are
 *  both now much simpler and cleaner.
 *
 *  JavaScript support has been added for more widgets.
