Updated Twoflower and better auth support

Holger released a new rev of Twoflower this morning, so I was able to update BottomFeeder to use it. This fixes some of the font issues (especially with bolded text) that had been present in the previous cut. I also received notice that Bf doesn't support urls that look like this:

http://username:password@www.somesite.com

That's shorthand for Basic Http Authorization - it's a way of providing the information up front instead of waiting to get prompted. The Http code wasn't parsing that out, and was instead barfing on that as an invalid url. I've addressed that in the latest update to the Http-Access module - that sort of url is now fully supported in the dev stream.
