Merge pull request #57 from jsocol/master

Expose version in elasticutils.__version__

This also renames elasticutils.VERSION to elasticutils.PYES_VERSION
to avoid convusion.
Only need one fake settings file
Fix django reqs file; add docs reqs file

This should fix autodoc stuff on ReadTheDocs.
Overhaul Django SearchMixin and docs

  have useful defaults

  and makes more of it correct

Issue 60. Implement terms query.
Issue 63. Fix bad field action silent errors

This fixes query processing so if you have an invalid field action, it
now raises an exception--just like filters.
Issue 66. Add test for __in filter field action
DEFAULT_INDEXES and DEFAULT_DOCTYPES are plural

These two defaults were wrong--they're both plural and should be a list
of strings. Other values are wrong.

This fixes that and also fixes a bunch of tests that broke because of it.
Fix Issue #53 - Implement more like this.

Adds a MLT class for making _mlt API calls.
Add Ricky to list
Tweak MLT code; add docs

* tweaks the MLT class so that s isn't required anymore
* adds an es argument
* adds documentation
* adds two more tests to make sure the s vs. index/doctype works
  correctly
Issue 54. Add docs for order-by

This also adds API documentation. It's not great because the docstrings
need work, but it's better!
Re-add index to TOC.
Tweak the search chapter title

Since it uses the ES Search API, it's better to call it "Searching
with S" rather than "Querying with S".
