add test case around ensuring proper field inference for boolean model field types
This fix results in models.NullBooleanField rendering as a checkbox in the browsable API
pass oauth_timestamp to oauth_provider
update requirements for django-oauth-plus to 2.2.1
add auth param to request client calls
SimpleRouter.get_lookup_regex got lookup_prefix

This allows @alanjds/drf-nested-routers to not duplicate/monkeypatch work made here
Fix default values always being False for browsable API

This fixes a bug that was introduced in 28ff6fb [1] for the
browsable API, specifically with how it handled default values
for boolean fields.  Previously, it had a global default for
boolean fields set to `False`, which was different than the
standard None that was used elsewhere.  Because this only needed
to be done for the browsable API, a fix was put into place that
only set the default to `False` when form data was passed into
the serializer.  This had the unintended side effect of overriding
any default set on the boolean field.

This fixes #1101 [2] by only overriding the default if the default is
`None`, which is the default for all fields.
