openal-soft: update to 1.15.1
dhewm3: add current master from github

This is a port of the Doom 3 source code released under GPL. Amongst others,
this makes use of SDL to be multiplatform, and supports amd64.
dhewm3: add mesa to build inputs

I also removed an unused line I left over in previous commits.
normalize 0.7.7: New package, an audio file normalizer
gmpc 11.8.16: New package, a GTK MPD (Music Player Daemon) client
postgresql: Make 9.2 the default

PostgreSQL 8.3 is end-of-life so it shouldn't be our default anymore.

The problem with changing the default PostgreSQL is that it breaks
NixOS installations that have PostgreSQL enabled without specifying an
explicit PostgreSQL version, because PostgreSQL does not do automatic
schema migration if the major version changes.

Thus, it's always a good idea to specify the desired major version
explicitly:

  services.postgresql.package = pkgs.postgresql92;

(In fact, maybe we should remove the default value for
services.postgresql.package.)
ffmpeg: adding manpage generation
Merge pull request #449 from cpages/dhewm3

Dhewm3: an SDL port of the Doom 3 GPL code
linux-3.0: upgrade to 3.0.71
linux-3.4: upgrade to 3.4.38
linux-3.8: upgrade to 3.8.5
linux-3.9: upgrade to 3.9-rc4
e17/e_dbus: make sure depending packages can find (propagated) dbus
e17/emotion: enable vlc video backend

we should probably make this configurable, but for now enabling (and
testing) at least 1 backend is better than none, as emotion without
backends won't anything at all
e17/ethumb: add optional dependency on e_dbus

ethumb_client depends on it, but will fail (skip on installation)
silently when not found
e17/ethumb: support video thumbnails and exif
add terminology: e17 terminal emulator
dhewm3: adding enableParallelBuilding
ffmpeg: update to 1.2 (and patching mplayer2)

Simple patch required by mplayer2 to build with ffmpeg 1.2.
dhewm3: linking with mesa (for non-nvidia cards)

It was just doing a dlopen(libGL), so mesa wasn't in the rpath.
Now it is.
