[keycloak-dev] theme changes and questions

I added a "logo-example" theme to the distro. This just provides a theme for login, account, and admin that overrides the logo (Keycloak image to Red Hat image). Because admin console is not based on freemarker templates, I refactored the admin console 'styles.css' to make it easier to override styles for the admin console. This now includes a 'base-styles.css' and a 'overrides.css'. The 'logo-example' theme for admin adds changes within 'overrides.css'. If you think this is the right way to implement this, I'll update the documentation to talk about how to override admin theme styles. -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
