Version bump for ruby-saml version

[ahills]

If you could make a release to include the updated ruby-saml dependency, I would much appreciate it.

@ahills I believe this still needs to be refined to require ruby-saml 1.1.1 or greater instead of just 1.1.0. See my comments here: #62 (comment)

[ahills]

When I installed from current master, ruby-saml-1.1.1 was installed.

That's expected behavior. However, if someone had a Gemfile.lock with 1.1.0, they could end up breaking omniauth-saml. I still think it would be good to prevent 1.1.0 from being installed explicitly since it's known to be incompatible with at least some SAML integrations.

I created #66 for this.

#66 was merged, which included ruby-saml 1.1.1 so I'm closing this one.
