CSS data-URI support for older IE versions about cassette HOT 4 OPEN

Don't know if you've done anything on this yet, Andrew, but I've made a start here (I haven't pushed to github yet as I have a pending pull request and don't want to mess it up).

So far I've changed the EmbedImages function to take an enum: {DataUri, IE8DataUri, Mhtml} so you can choose to have full embedding or not. Mhtml rendering is next!

I've not started any work on this yet, so I'd be very happy to see a pull request :)

Interesting dilemma: mhtml urls need to be fully qualified absolute paths:

url(mhtml:http://www.phpied.com/files/datasprites/datasprites2.php!aol)

This means we need to know at render time what the url of the css file will be. Now, I can get the local part of the path from the UrlGenerator, but the http://www.example.org part will need to either be pulled from IIS somehow or entered as a configuration entry somewhere. I'm in favour of adding a property to the StylesheetBundle that will be the fully qualified domain name used by the MHTML embedding.

Any thoughts?

Yeah, that's a potentially tricky issue. Go with whatever's simplest for now.

I imagine Cassette.Web.Startup will be able to get the domain name from the current HttpContext, but I may need to check this doesn't happen before HttpContext has been assigned.

If you can get your fork working with something basic for now, I can look at the fiddly integration stuff. Thank :)
