------------------
Feature:
* Support regular expression paths and path includes
* Add plugin system to the converter for third-party extensions
* Add django-ninja converter plugin for ``NinjaAPI`` and example
* Add docs for writing converter plugins
Changes:
* Command line argument order has changed from ``<script> <cmd>`` to ``<cmd> <script>``
* Script can now be specified as a module, eg ``foo`` instead of ``foo.py``
* Django instance no longer needs to be ``app`` - its name can be specified as
``<script>:<name>`` (eg ``counter:myapp`` or ``counter.py:myapp``), or can be
auto-detected.
* ``ADMIN_URL`` is now optional - the admin site will be enabled if there are any admin
decorators present
Internal:
* Remove redundant cleaning of leading slash in paths
* Improved gitignore
