Support xmlns tags

[eazel7]

Provide support for tags with namespaces I created a small patch that has a stack of namespace prefixes. It also contains a test for:

<root xmlns:a="my:ns">
  <a:alien>Thing1</a:alien>
</root>

which emits tag:my:ns alien event. Notice the space between the namespace uri and the tag name. I chose the space because it's not a valid tag name character.

@eazel7 Thanks for the pull request. Before I can merge it in, I need to look into the build failures and think through tests/documentation... Unless you'd like to give it a try?
