Jan Malakhovski e4a4e109ba refactor Emacs packages'/modes' builders
This simplifies melpa builder by merging with it my old emacs modes builder,
adds better instructions and support for overrides in emacs-packages.nix,
and renames some emacs-related stuff in all-packages.nix for sanity reasons.

I declare this backwards compatible since direct uses of emacsPackages in
configuration.nix are very unlikely.
