[Radiant] Yeilding Snippets

Sean, thanks for your reply. I thought there would be more to it than  
that, but you made it sound easy, so I gave it a go. Here is the ticket:

I wasn't sure how to save tag.expand in a local so that it was  
accessible from <r:yield/>, so I've cheated a little:

	snippet.content.gsub!(%r{<r\:yield\s?/?>}, tag.expand)

and making <r:yield/> output nothing. It's not exactly idiomatic, but  
it passes the tests!

Cheers,
