[keycloak-dev] Add title for Realm, Applications, Clients and Roles

[Stian Thorgersen]

I propose we add a title for Realm, Applications, Clients and Roles. In admin console, login forms and account management we should then use the title if specified, otherwise use the name.

This allows having a URL friendly name (for example "realm-one") while having a human friendly title for interfaces (Realm One).

Any objections?
