Introduce Django 1.4 compatibility
Removed unneccesary PGThread.

Django connections are thread locals by default, it's safe to attach
attributes to the DatabaseWrapper, because those are thread safe.
Removed connection.get_schema() and connection.get_tenant() methods,
those were not very pythonic at all. Use connection.schema_name and
connection.tenant properties instead.
Merge branch 'master' of github.com:bernardopires/django-tenant-schemas
Resolved merge conflicts on docs regarding tenant and schema_name
readded backwards compatibility (get_schema_name and get_tenant)
fixed get_schema_name not being called get_schema
Merge pull request #90 from aniav/master

Fix tests, move from PUBLIC_SCHEMA_URL_TOKEN to PUBLIC_SCHEMA_URLCONF
