[keycloak-dev] dynamic key look and relative uri support added

[Bill Burke]

* For adapter config, you can now leave out the realm's public key as 
long as you have a valid auth-server-url.  Keycloak will now ping this 
auth server to obtain the public key for the realm.

* The adapter config supports a relative URI for the auth-server-url. 
It will use the current requests scheme, host, and port to create urls. 
  A relative url examples is: "/auth"

* The auth server supports relative URLS for redirect urls, admin urls, 
and base urls.  i.e. "/customer-portal/*".  The current request is used 
to to build the redirect url to validate against,  THe scheme, host, and 
port is used.

With these changes, it makes it a bit easier to bundle preconfigured 
apps and keycloak on a single server.  Hoping this will resolve a bunch 
of Aerogear issues.
