[TYPO3-core] RFC #9474: Integrate OpenID authentication support to TYPO3

[Steffen Kamper]

Hi Dmitry,

+1 based on reading and testing. I tested it while hackontest as i followed
your commits, saw the video and tested with the hackontest-branch. You did a
great job, the manual is very good too.

I'm for openid as sysext as i think this kind of alternative authentication
should work "out of the box"

btw - extkey"openid" is registered by julle, you should talk to him.
