Add bitmap gradient for ie background

Matt, this will fix the background stuff in ie. I could only check the homepage because of rails errors but it should do the trick.

As far as the fonts I think you are going to have to mess with the headers when the font is requested. If you check out http://www.dimensionedelta.net/block/tests/font-test.html and look at the Content-Type it comes across as <code>application/x-font-woff</code> from your app the font request comes across as <code>application/octet-stream</code> so I think that is tripping up ie. I think if you get that squared away you should be good.

Lemmie know if you need anything else.
