added optional host and max_children args to scgi's serve_application.

Ideally the function prototype would match SCGIServers, i.e.:

def serve_application(application, prefix, host=, port=None, max_children=None):
or:
def serve_application(application, prefix, **kwargs):

(host, port and max_children could then default to SCGIServer's defaults),
but that could break compatibility with those not explicitly using
keyword args
