Update gitignore for setuptools files
Space imports properly
Rejigger return value of apply_queryset_options()

This method was returning a 3-tuple of (object_list, length,
filtered_length), which was required information, but was
counter-intuitive when serialize_to_json() was having to unpack its
single argument into three separate ones.

This solution preserves the single argument format, which is a list
subclass with data attributes on it.  This approach was chosen to
prevent the renaming of the get_object_list() method to something less
comprehensible.
Move JSON object generation to new method

This addresses the need to potentially return additional data fields in
the response for client-side operations.

serialize_to_json() now takes the python dictionary of data compiled by
the new get_json_response_object().

Remove JSON indentation when DEBUG=False

This was originally a debugging measure, but shouldn’t be applied in
production scenarios.
