xrmx: s/Submit/Search to keep parity with django upstream
Update CHANGELOG

Fix #155
bootstrap3: Fixup deprecation warning

RemovedInDjango18Warning: Options.module_name has been deprecated
in favor of model_name

Fix #154
Update CHANGELOG
Bump release to 2.1.1
bootstrap3: move static and templates back to main app

While in theory would be cool to support multiple bootstrap version
in practice it's not.
First bootstrap upstream support only one version at time, then the
name already clashes with at least another django application.
README: bootstrap3 application is not required anymore
Upgrade bootstrap to 3.3.0
Update CHANGELOG
Update bootstrap to 3.3.1
Add missing semicolon
Update CHANGELOG
bootstrap: cleanup indentation in search_form

Fixes #144
Update CHANGELOG
Bump version to 2.2.0
Fixup hover on "add new model" button

Fix #156

Inner navbar is a bit off in < 1024px screens though.
