Django-popupcrud

++++++++++++++++++
* List view content is rendered in its own block, popupcrud_list, in the
template file. This allows the list content to be relocated to different
parts of the base template.
* Add ViewSet.empty_list_icon and ViewSet.empty_list_message properties. These
properties provide for prettier rendering of empty table states.

++++++++++++++++++
* Bumping minor version as reflection of new features legacy_crud dict, media
& out-of-the-box django_select2 support in previous release
* Added 'crudform.ready' JavaScript event, which is triggered when
create/update form is activated. This event provides clients an uniform way to
apply their own optional initialization code to the CRUD forms.
* Added 6 more tests to cover new legacy_crud dict value support & form media
injection.

++++++++++++++++++

* Add PopupCrudViewSet.urls() -- a single method to return all the CRUD urls
that can be added to urlpatterns[].
* When related object popup is activated on a multiselect select and it adds a
new object, the object is added to the existing list of selections. (old code
used to replace all the current selections with the newly added item)
* Insert all form media into ListView through ListView.media property.
* Fix broken support for django-select2 in modals by setting control's
dropdownParent to the modal (rather than parent window)
* Use the 'create-edit-modal' modal as the template for secondary modals
activated through related-model modal popups. This ensures consistent modal
look and feel if the user customized the modal template by overriding
popupcrud/modal.html template.
* Fix ALLOWED_HOSTS in settings - issue 1

++++++++++++++++++

* Object detail view support

++++++++++++++++++

* Better access control support through 'login_url' & 'raise_exception'
PopupCrudViewSet properties

++++++++++++++++++

* Better unicode support
