APIException: ability to pass status_code to __init__ method

[syberen]

Relevant excerpt from the APIException class:

class APIException(Exception):
    status_code = status.HTTP_500_INTERNAL_SERVER_ERROR

    def __init__(self, detail=None, code=None):
        ...

If we can instantiate this class with a detail and error code, it might also be convenient to pass a status_code. Then it wouldn't be necessary to subclass to get a custom error response.
