Implements model save options, issue #110
Adds page title to model create page
Adds model name to AdminModel2Mixin template context.

All views subclassing AdminModel2Mixin will need the model
name in their template context, so moving it to the base
class so child views don't all have to override
get_context_data.

Adding @chrislawlor to the list of authors.
Add 'title' and 'page_title' template blocks.

Fix delete text to match original admin.
rename admin2_urls to admin2_tags
Merge remote-tracking branch 'origin/develop' into rename-templatetag-module
Match master to develop
Use admin2_url, redirect create form to index view.

Uses the template tag admin2_url to create namespaced view names
from inside of views.

Create model form now redirects to the model index page, as
django.contrib.admin. does.

Removed get_success_url from ModelListView, as generic.ListView
does not call this method.
