NWR04B: First release

I've put together a couple downloads for the NWR04B. The first is the whole tarball of source code -- BusyBox, uClinux, plus some glue. You can use this to compile your own images. It's about 29MB. The second is just the bare minimum: the firmware image, the root directory for the router, and some instructions. It's about 685KB. You can find both of them here: http://saintaardvarkthecarpeted.com/nwr04b/download The downloads have been signed with key 0x4705C9C7 and checksummed with SHA1.
