nixpkgs: Add manpages to aszlig-env.

Might come in handy if you want to look up documentation to syscalls or libc
calls.

common.nix: Add user "aszlig" by default.

This is especially useful in case someone wants to build the system from scratch
and doesn't remember group memberships anymore.

common.nix: Add a few more system-wide packages.

I use things like compression tools, psmisc (esp. fuser), file, vlock and htop
as other users (well, "root" comes in mind ;-) as well, so it makes sense to
make it available system-wide.

nixpkgs: Update to kernel 3.8.0-rc2.

3.8.0-rc1 is quite old, so we really _need_ to upgrade, right? :-)

nixpkgs: Move package list into ../collections.

collections: Avoid repetitious use of "with pkgs".

common.nix: Start GnuPG agent by default.

I still don't see the reason to start the OpenSSH agent by default, because
GnuPG has SSH agent support built-in as well. So, let's disable the SSH agent.

mmrnmhrm: Provide fixed default XRandR properties.

In my case this is just dual head for this machine. Synergy is not yet added to
the NixOS configuration, but this is in preparation for it to work.

mmrnmhrm: Add synergy call and configuration.

So, now we no langer need to issue synergys by the window manager or in the
shell, just log in and everything is set up :-)

Well, of course you should only do something like this in a trusted environment,
because this means, that mouse movements and keystrokes are sent unencrypted! Be
sure to set up a SSH tunnel or something similar if you're in a hostile
environment.
