    Merge pull request #2 from mjtamlyn/lookups_3

    Reworked custom lookups docs.

commit f2dc4429a1da04c858364972eea57a35a868dab4
Author: Marc Tamlyn <marc.tamlyn@gmail.com>
Date:   Sun Jan 12 13:15:05 2014 +0000

    Reworked custom lookups docs.

    Mostly just formatting and rewording, but also replaced the example
    using ``YearExtract`` to  use an example which is unlikely to ever be
    possible directly in the ORM.

    Altered query string customization for backends vendors

    The new way is trying to call first method 'as_' + connection.vendor.
    If that doesn't exist, then call as_sql().

    Also altered how lookup registration is done. There is now
    RegisterLookupMixin class that is used by Field, Extract and
    sql.Aggregate. This allows one to register lookups for extracts and
    aggregates in the same way lookup registration is done for fields.

    Initial implementation of custom lookups
Fixed #21659 -- Modified the registration/password_change_form.html admin template to use {% admin_static %}.

Thanks mcella.
Fixed #21794 -- Adjusted warning for abstract models.

As far as I can tell, they don't need an app_label.

Thanks Simon Charette for the report and the review.
Fixed #21821 -- db_type argument for field_cast_sql

The db_type argument for connection.ops.field_cast_sql wasn't correctly
set after merge of custom lookups patch.
Fixed typos spotted by Claude Paroz
Stopped assuming that INSTALLED_APPS only contains app names.

While this assumption is true for the time being, it makes the code
needlessly brittle.
Fixed #21712 -- Moved autodiscover() to AdminConfig.ready().

Thanks Marc Tamlyn for the initial version of the patch.
Refs #21628 -- removed one usage of the imp module in the tests. It is deprecated in Python 3.4
Fixed Oracle query failures caused by lookup refactor

Refs #21821.
