- Add latest gdata libs (1.45.0) with source code - cleaned the publishing context files out of the top-level application context - removed the notion of "content root" from publishing channels - added YouTube publishing channel with actions to publish and unpublish - added dummy channel types to ease UI development git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@28575 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
