load stylesheets async

[GoogleCodeExporter]

We could extend this to load stylesheets async. If I have a big stylesheet that 
only contains styles for some later feature (eg, the "compose" UI for web 
email) it would be nice to download that later when it's needed since it can 
block rendering in some browsers (including IE).

Yes this would be very great to be able to load stylesheets and also do not add 
them to the document before needed (preloading without executing)

Then when we need that big popup with lots of images : execute it
