Updated ignores.
BACKWARD-INCOMPATIBLE: Removed ``RealTimeSearchIndex`` in favor of ``SignalProcessors``.

This only affects people who were using ``RealTimeSearchIndex`` (or a
queuing variant) to perform near real-time updates. Those users should
refer to the Migration documentation.
Fixed the imports that would stomp on each other.

Thanks to codeinthehole, Attorney-Fee & imacleod for pointing this out.
Further docs on autocomplete.
That second colon matters.
Fixed the docs on debugging to cover v2. Thanks to eltesttox for the report.

Pass active backend to index queryset calls (closes #534)

Now the Index index_queryset() and read_queryset() methods will be called with
the active backend name so they can optionally perform backend-specific
filtering.

This is extremely useful when using something like Solr cores to maintain
language specific backends, allowing an Index to select the appropriate
documents for each language::

    def index_queryset(self, using=None):
        return Post.objects.filter(language=using)

Changes:
    * clear_index, update_index and rebuild_index all default to processing
      *every* backend. ``--using`` may now be provided multiple times to select
      a subset of the configured backends.
    * Added examples to the Multiple Index documentation page
