abiword: Fix glib/gdx_pixbuf related build errors.

A bunch of these includes expect extra prefixes which we don't have in Nix, so
we are going to batch-fix them with sed.

abiword: Enable parallel building.

Shouldn't take _that_ long to build, but I was impatient during fixing the
build and it doesn't hurt anyway, does it?

hping: New package, version 20051105.

Quite a lot of patching involved here, but the upstream package is no longer
maintained anymore. Nevertheless the tool is still useful in some environments.

wbox: New package, version 5.

Yet another HTTP benchmarking tool, which is really quite minimalistic and in
ANSI C.

This package maybe isn't even worth putting it in its own file and directory but
I did it for the sake of consistency.

git-and-tools/hub: New package, version 1.10.3.

This is a small wrapper of Git, which integrates some GitHub specific features,
especially stuff like merging or sending pull requests or attaching commits to
an issue.

I'm not quite familiar with the Nix integration of Ruby, so let's hope that I'm
not doing something horrible here.

samplicator: New package, version 1.3.7-beta6.

A small and lightweight UDP redirector if you don't want to bend a fly on the
wheel using socat.

vbindiff: New package, version 3.0_beta4.

Visual binary differences viewer, very useful for reverse-engineering
proprieritary file formats.

virtualbox: Allow building with extension pack.

The extension pack is needed in order to have USB 2.0, RDP and PXE boot support
and is _not_ part of the free version, so please read their conditions before
using it:

https://www.virtualbox.org/wiki/VirtualBox_PUEL

Further information and details about the extension pack is available here:

https://www.virtualbox.org/manual/ch01.html#intro-installing

I'm wimping out here and use requireFile to ask the user to fetch the extension
pack manually, simply because I'm not a lawyer. I've seen other distributions
that fetch the extension packs directly from upstream, but I'm not sure if that
is according to Oracle's PUEL.

xinit: Fix logpath and dependencies for startx.

It seems that (almost?) all NixOS users start X using the services module,
because startx seems to be broken for quite some while. And it hit me while
getting to NixOS for the first time as well, so I then decided to just use the
service module.

As I'm working with multiple X servers, writing wrappers in ~/nixpkgs/config.nix
became tedious and so I decided to fix it, hopefully without breaking anything.

The fix consists of:

 * Provide a default location for the Xorg log (~/.xorg.log - hope that's okay)
 * Expose xauth through xinit to ensure purity and "unexpected behaviour", also
   known as "simply not working", because xauth isn't in the user's environment.
 * Actually provide the X binary so it doesn't have to be passed to startx every
   time.

ascii: New package, version 3.12.

Quite a useful tool, especially for non English native speakers to find out what
people mean with things like "hiccup", "boink", "blugle" and whatnot.

And of course it's quite useful to convert between hex/oct/dec/bin.

chromium: Update stable and beta channel.

stable: 23.0.1271.95 -> 23.0.1271.97 (tested and works)
beta: 24.0.1312.27 -> 24.0.1312.35 (tested and works)

The dev version doesn't build in its newest incarnation, so we will need to fix
and/or patch it before pushing upstream.

scid: New package, version 4.3.

Just saw Michael Raskin's GNU Chess and XBoard updates and did a short check if
Scid is already in nixpkgs. It wasn't, so I decided to add it, so thanks to
@7c6f434c :-)

The package involves a lot of patching, as usual with Tcl/Tk on NixOS. In this
case the program is written in C++ and embeds the Tcl/Wish interpreter.

Unfortunately this doesn't make it easier to inject TCLLIBPATH, as there doesn't
seem to be a direct library call (well in theory you could `lappend TCLLIBPATH`,
but that won't help with TK_LIBRARY).
