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.
Merge PR #901: adding Storm

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