libvte: fix .la file to include the libpath for ncurses

Without this patch, the .la file only added -lncurses without
specifying the nix store path, forcing the propagation
of ncurses as build input.

Also enable parallel building and add myself to the maintainers.
haskell-codex: updated 0.1.0.0 -> 0.1.0.1
python-packages: Add package 'sure', v1.2.7.

Unfortunately the upstream version that can be found on PyPI doesn't
include test cases, so we need to fetchgit and wait until tests will be
shipped with a future upstream release.

Reported at gabrielfalcao/sure#61.

python-packages: Add package 'httpretty', v0.8.3.

This contains a context diff because the change is really very small and
gabrielfalcao/HTTPretty#180 cannot be used because it bumps the version
number.

The reason I'm not using sed here is because I deliberately want the
postPatch phase to fail for the next upstream version, so the patch/fix
is dropped on our side ASAP.
