egroupware_official/etemplate/inc/class.editor.inc.php
Ralf Becker daceac54ad Added interface to extend eTemplates with new widgets.
The widget got automaticaly loaded from the app's inc dir (or etemplate's inc dir).
Two examples ilustrate how to use the interface:
 - date: class.date_widget.inc.php reads dates via sbox.getDate
 - datefield: class.datefield_widget.inc.php reads dates via 3 textfields
