Fixed 2 compiler errors and 1 warning on rustc 0.8-pre (6bc48b6 2013-09-16 09:00:44 -0700)

Updated syntax in two places, which enabled me to remove an import, which I did. Now, running 'make' does not show any errors and it shows only one warning, which tells me to file a bug report against Rust, so it probably has nothing to do with rust-http.
