Integrate ECP as optional/default way of talking to IdPs (if they support it)

[makkus]

ECP: https://wiki.shibboleth.net/confluence/display/SHIB2/ECP

would be good if sibboleth could auto-detect whether ECP is available and use it if...

Ideas? Suggestions?

Hey Markus,

I can help you with this. I have a python slcs client I whipped up that does ECP.

I also have a way of figuring out if an IdP can do ECP or not.
