Fixed an update_index bug when using multiple connections
Use Django's copy of six
Reset backend state when deleting index

Reset setup_complete and existing_mapping when an index is
deleted. This ensures create_index is called later to restore
the settings properly.
Test ensuring recreating the index does not remove the mapping
Merge remote-tracking branch 'infoxchange/fix-elasticsearch-index-settings-reset'
Fixed ordering issues in the ElasticSearch tests.
Added some faceting tests for ElasticSearch.
More ElasticSearch test fixes.
Added a spelling test case for ElasticSearch.
Fixed my own spelling test case. How embarrassing.
update tox to test pypy, py26, py27, py33, django1.5 and django1.6

django 1.6 doesn't actually work yet, but there are other efforts to get that working
pass `using` to index_queryset for update
Update solr schema template to fix stopwords_en.txt relocation

Seems that in versions >3.6 and >4 stopwords_en.txt moved
to a new location. This won't be backwards compatible for
older versions of solr.

Addresses issues #558, #560
In addition, issue #671 references this problem
switch solr configs to solr 4

almost all tests passing, but spatial not working
[tox] run tests for 1.6, fix test modules so they are found by the new
test runner.

These changes are backwards-compatible with django 1.5.  As of this
commit, the only failing tests are the Solr extractraction test, and the
spatial tests.
fixed simple backend for django 1.6, _fields was removed.
fixed basepython for tox envs, thanks --showconfig

also, added latest django 1.4 release, which doesn't error out
currently.

Downgraded python3.3 to python3.2, as thats what the lastest debian
stable includes.  I'm working on compiling pypy and python3.3 on the
test box, so those will probably be re-added as time allows.

failing tests: still solr context extraction + spatial
Fixed autocomplete() method: spaces in query
added test for autocomplete whitespace fix
