[TxMt] HTML-ish bundles

[Rob McBroom]

I noticed that there's an XHTML bundle in the repository and then  
there's the HTML bundle included by default. I'm wondering, if  
there's an XHTML bundle, why does the default HTML bundle use XHTML  
in its snippets? Can we move that nonsense into the XHTML bundle and  
let those that want it install it? (Perhaps it should be included by  
default as well.) Just curious.
