Extensible CheckBox List

Introducing a brand-new widget for TurboGears: Extensible CheckBox List!

To use it:

1. easy_install xcbl
2. In your controller.py,
   from xcbl.widgets import ExtensibleCheckBoxList
3. In your form's WidgetsList,
   pets = ExtensibleCheckBoxList(options=['cats','dogs','turtles'])
   (exactly the same as you would for an ordinary CheckBox List widget)

The result - a CheckBox List with an "other" field that lets the user hand-enter new options - as many as they want.

Unfortunately, the new items will appear beneath the "Other:" box, not above it, unless you upgrade your MochiKit to 1.4. Details on how to do that and more are here.

Developing it was lots of fun - it really shows how easily a relative amateur can contribute to TurboGears. I hope to write up a "Developing and Contributing TurboGears Widgets for Dummies" document soon, based on the experience.
