Releases for OpenID Provider

A final stable release, at last! See this post for context and a longer story.

We finally bundle:

Small release to fix the nonce and keep sync with D7 releases.

* #1423658: make a stronger nonce

This is yet another bugfix release! Onwards to the real 1.0 :)

With this release we complete the checkid_immediate implementation and perform further code cleanup. With this release, there remains no TODOs directly in the code (although some things are still missing, according to the README).

I think we are ready for a release candidate. This module now works on all RP I can try and I have cleaned up the code significantly.

More bugfixes!

* #1234214: bccomp error if the gmp library is installed
* #1419910: fails to login on redmine

Some code cleanup was also performed.

Give up on redmine and fix logins on stackoverflow, which seems to be following the standards: #831162: cannot login on stackoverflow or dotnetopenid sites

Port to 7.x. No functional change.

Changes since 1.0-beta2:

Initial beta release for 1.0 (at last!) - addresses #331653

TODO before 1.0 final - ensure compatibility & full spec compliance. Patches and testing welcome!
