Change in parameter name
Avoid duplicated or to some extend faulty information.
Loading a MD file was faulty.
Read metadata from somewhere and dump it in the MD format.
Made it possible to accept a success Response without Attribute and AttributeValues.
Switched to use a simple monotonic increased identifier for authn types.
'Return' is the correct parameter name in discovery.
Not completely clear of which of HOST_NAME or SERVER_NAME is correct to use.
Support for metadata mdfile type
Better english!
Return is a protected python word so it can not be used as a parameter name in a method definition.
These fixes are there to allow for the usage or return_url or return as parameter name.
In some case you want the url to be based on server_name/server_port and not http_host, now you can get what you want.
Changed version number to allow for new release.
verify_request: fix return data.

Calling code expects two element tuple returned.
