Richard Zetterberg 2206d7afe2 texlive manual: adds import of nixpkgs in nix-repl
I wanted to list the different texlive collections using the nix-repl, as per the [manual](https://nixos.org/nixpkgs/manual/#idm140737316065984). 

It didn't work, since the nixpkgs were not loaded. Doing `:l <nixpkgs>` first resolved the problem.

This change adds the nixpkgs loading step to the manual so that the next inexperienced person don't have to figure out why it didn't work.

I tested this on NixOS unstable (16.09pre90254.6b20d5b) with nix-repl 1.11.3.

It typically won't work to use separately installed packages together.
Instead, you can build a custom set of packages like this:
<programlisting>
texlive.combine {
inherit (texlive) scheme-small collection-langkorean algorithms cm-super;
}
</programlisting>
There are all the schemes, collections and a few thousand packages, as defined upstream (perhaps with tiny differences).
</para></listitem>
<listitem><para>
By default you only get executables and files needed during runtime, and a little documentation for the core packages. To change that, you need to add <varname>pkgFilter</varname> function to <varname>combine</varname>.
<programlisting>
texlive.combine {
# inherit (texlive) whatever-you-want;
pkgFilter = pkg:
pkg.tlType == "run" || pkg.tlType == "bin" || pkg.pname == "cm-super";
# elem tlType [ "run" "bin" "doc" "source" ]
# there are also other attributes: version, name
}
</programlisting>
</para></listitem>

You can list packages e.g. by <command>nix-repl</command>.
<programlisting>
