Added printing capabilities in Internet Explorer.

Added "cf" namespace which IE needs in order to recognize non-standard DOM elements.
When printing, only hide "cufontext" elements, not the entire canvas.

Hi,

Thank you for the patch, much appreciated. However, we don't have any automated tests to make sure that this change doesn't break any other browsers... The lack of tests was what eventually made the project too difficult to manage, causing the current state of near-abandonment.

I think supporting ancient browsers remains one of the very few legit use cases to keep using cufon, so I'm a bit vary about doing anything at all.

Could you confirm which browsers (and versions) you tested this with?
