Namespace support

Hi all,

I just committed a bunch of code to support custom xml namespaces and
added a MessagingNamespaceHandler as an example (which I'm also using
in a project right now but which is not 100% complete). In addition to
that, I have also changed the default namespace to
spring_actionscript_objects and updated all classes and tests
accordingly.

This required some changes to the main parser which could potentially
break the framework. I was able to successfully run all tests but I
would appreciate any feedback from people who are working with the SVN
sources.

Until the new schema's are uploaded to the springactionscript.org
domain, you can find them here:
- http://www.pranaframework.org/schema...bjects-1.0.xsd
- http://www.pranaframework.org/schema...saging-1.0.xsd

Here's an example xml declaration using the new namespaces:

<objects
xmlns="http://www.springactionscript.org/schema/objects"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:messaging="http://www.springactionscript.org/schema/messaging"
xsi:schemaLocation="
http://www.springactionscript.org/schema/objects
http://www.pranaframework.org/schema...bjects-1.0.xsd
http://www.springactionscript.org/schema/messaging
http://www.pranaframework.org/schema/messaging/spring-actionscript-messaging-1.0.xsd"/>

In order to use a custom namespace, you need to register it via the
"addNamespaceHandler" method on the application context before loading it.

Have fun!

Christophe
