Atlassian Crowd Authentication

Sure, you can wire up Grails with Acegi and the new Crowd-Acegi integration APIs released with v1.3, but that is way too much work. This Grails plugin has no dependency on Acegi, and talks to Crowd directly for its authentication and authorization requirements. The plugin borrows ideas from Grails Authorize for the simple auth/auth configuration, and from Grails Acegi for a GSP taglib.
