d-i beta 2

It feels like this took too long, but beta 2 of d-i is in the process of being released for three architectures. Now we need to figure out what to do about the 2 and a half architectures that did not quite make this release, and where to go from here. Should be interesting.

A big thank you is due to everyone who made this d-i release possible. With especial thanks to the several ftp-masters who have helped us in a number of ways. You guys rock!
