Changed search (and track) API to tastypie.
Added two tests files for the queue API

The two files can also serve as example for users.

Also added a serializer that can be extended with our specific formats.
Updated setup.py to include tastypie and removed social auth
Updated README.
Moved API initializing to django-tastypie.

The API URL adding works the following way:
	radio_django/api.py imports all handler files we create. By doing this the
	handler file can register its resources with the `container` in `api.py`.

	This makes all the resources register before the importing of `api.py`
	actually finishes. That way we can be sure all the resources are
	registered before adding them to our URLConf. Otherwise the resources
	registered highly depend on Django's bootstrap.
