Add jzmq package.
Add storm package.
Make Storm conf and log path configurable via symlinks.
  - The bin/storm script makes too many assumptions about file locations and java classpath that I couldn't figure out a better way.

Fix jzmq build on NixOS: java source was treated as ASCII.
Improved Storm package.

- Add config to defaults.yaml, to allow topologies to include their own storm.yaml.
- Symlink extra jars in lib/ since it's nearly impossible to add a classpath to Storm's config.
- Include native jzmq library in java.library.path
- Use package default args.
I henceforth will maintain as my Github username.
Yes.
libav: update 9.8 -> 9.9

It's supposed to include some security-related fixes.
upgrade deform and deform_bootstrap
Update nixUnstable
Fix Nixpkgs evaluation

The evaluation of liferea causes an error:

  error: assertion failed at `/tmp/nix-build-nixpkgs-tarball-1.0pre28992_1628c03.drv-0/git-export/pkgs/desktops/gnome-2/desktop/libgweather/default.nix:4:1'

Why this happens is a mystery, since liferea doesn't depend on
libgweather.  The problem can be reproduced by evaluating:

  builtins.toXML (import <nixpkgs> { system = "x86_64-darwin"; }).liferea

It seems to have something to do with builderDefs magic in webkit_gtk2.

vcunat edit: use symlink instead of hardlink (failed for me with a
cross-device error), minor whitespace cleanup
