Update CHANGELOG
Fix celery requirement
Cosmetic indentation fix
Update to 0.8 for release; peg pyelsticsearch

We're pegging to a specific version of pyelasticsearch since they've
done a release that had backwards-incompatible changes.

Updated the release process accordingly.

Moved requirements files to their own directory to clean things up
a smidge.
Fix MANIFEST and setup.py bits
Update version to 0.9.dev for development
Use correct default value for the overwrite_existing parameter.

See https://github.com/rhec/pyelasticsearch/commit/88950a96583e538f9d38f4e356a995819a4739ac#L2L288
Merge pull request #169 from jezdez/patch-1

Use correct default value for the overwrite_existing parameter.
Update CHANGELOG; fix docstring typo
Fix silly typo in CHANGELOG
Fix query_raw -> filter_raw in CHANGELOG
Add comment about changing defaults

I think this satisfies the problems detailed in pull #171, namely
these are "constants" created at module-load time, are internal,
aren't part of the API and thus shouldn't be changed by people
using ElasticUtils.
