chromium: Link against pulse instead of dlopen().

This fixes the issue of Chromium not being able to load the pulseaudio
librarp

We could also propagate the build inputs, but it would end up being the
same as just directoly linking against the library.

Thanks to @aristidb for noticing this in #2421:

all-packages.nix: strip trailing whitespace
R: added wrapper script that provides "R" and "Rscript" binaries that know about extra libraries

Configure an override in ~/.nixpkgs/config.nix as follows:

  {
    packageOverrides = pkgs: {

      rWrapper = pkgs.rWrapper.override {
        packages = with pkgs.rPackages; [ Defaults dataTable foreach xtable ];
      };

    };
  }
r-packages.nix: added various new libraries

Changed URL to upstream, as the old URL was dead
r-packages.nix: add an auto-generated list of all CRAN packages
all-packages.nix: move all R-related attributes into one place
cosmetic: move the R-wrapper into its own directory
Move r-packages.nix into the r-modules directory.
R: don't install the "recommended packages"

These packages come with R, but if we install them as part of this build, then
we cannot update them without re-building R as well. Instead, we add those
packages to the R environment through the r-wrapper. This means that
recommended packages can be updated in cran-packgaes.nix, and those updates
have an effect on the installation without re-building R itself.
haskell-defaults: prefer cabal-install 1.20.x on ghc-head
