Some clients seem to include CRLF in the POST' Content-length, some don't. Ignoring when clients send more data then advertised and stripping CRLF at the end works fine across firefox, w3m and netsurf.

w3m (HTTP/1.0) doesn't seem to like it.

It's a first stab at it, some planned features (like the search) are missing but the basic ones work. It's not hooked in the main build yet.
