#4 Updates to BB Contrib for version 0.9

[Brad Baker]

I have posted an updated ZIP file of the
TabbedPane, ExpandableSection, ListSection,
DatePicker and ColorChooser classes.

They have been updated to reflect the new 0.9
version of the core echo API.

They now support the new "applyStyles()" method
for setting many styles at one time.

They also implement Serializable where necessary
(specifically in the DefaultModel classes).

The Connection patch required for TabbedPane is
not longer required as the new 0.9 version of the
class libreary now exposes the getRequest()
method as public.

The new ImageManager class is used now in all
classes to provide images.

A cursory check of performance would indicate that
the new 0.9 class library is indeed faster. Please
note that I havent done an exhaustive test of this.
