vim: supporting multiple sources:

- vim-nox: client-server implementation without X
- latest:  latest mercurial sources (still very stable)
- default: latest release

vim-plugins: Introduce an area to put vim plugins which are worth adding to nix
because they need more effort than just "unpacking". Document that
