Django-autocomplete-light

- Implemented autocomplete_names support to override the default
Autocomplete class used for a given model form field,
- Make the first Autocomplete class the default autocomplete (for generic
and model).
- Implemented lazy autocompletes: you can refer to an autocomplete class
before it is discovered.
- Import TaggitField and TaggitWidget in autocomplete_light.

- Fix 219: autocompletes now convert None value to an empty list, as
Autocomplete promises that values is a list. (Fixed gfk in inlines)
- Fix 226: improved css/js positioning.
- Fix 231: widget.js was re-initializing widgets.
- Fixed taggit support
- Fix: label was not set for gmtm and gfk in inlines.

- Updated pt_BR translation contributed by Fábio C. Barrionuevo da Luz (luzfcb).

- Removed a layer of complexity by trading autocomplete_js_attributes and
widget_js_attributes for attrs (for input/autocomplete object) and widget_attrs
(for widget container/widget js object).
- Fixed naming conventions issues:
- 124: css class .choiceDetail should be .choice-detail, same for
.choiceUpdate
- 97: rename .div css class to .block,
- Fixed 84: data-autocomplete-placeholder is gone in favor of the
placeholder attribute.
- Fixed 82: data-* is not parsed anymore by yourlabs.Widget, data-widget-*
is parsed for options instead.
- Fixed 81: js Autocomplete object now parses data-autocomplete-* for
options,
- Fixed 80: js maxValues is now maximumValues.
- Fixed 27: refactored selenium tests to be able to test any example app.
- Bugfix: get_autocomplete_from_arg returned wrong autocomplete in two cases

- Simplified widget template selection.

- Support for Django 1.6's ModelForm.Meta.fields = '__all__', generic fk
and generic m2m autocomplete fields were not created.
