local-openid 0.3.0 - compatibility improvements

This release brings a major compatibility improvement
from Lionel Elie Mamane:

  The OpenID provider identifier and user identifier are now
  distinct and compliant with the OpenID 2.0 specification.

  The user identifier is unchanged: http://${HOST}/
  The provider identifier (and provider endpoint URL) is now
  http://${HOST}/provider

If you were not able to get local-openid working with a certain site in
the past, this version may work for you.  Please report any
compatibility problems to local.openid@librelist.org and hopefully
somebody can help.  Unreported issues can never be fixed.

The Sinatra dependency is relaxed to allow any 1.x version
(tested with 1.3.2 and 1.0.0).
