Merged BRANCHES/DEV/BRIAN/PUBLISHING to HEAD:

29482: Publishing:
   - Added support for LinkedIn status updates
 29486: Social Publishing UI Updates, including:
   - Dialogue: Complete UI rework
   - Publishing History: display of unpublish event support
   - Created Alfresco.util.toggleClass function
 29491: Publishing:
   - Added correct list of supported MIME types the the YouTube channel type
 29493: Publishing:
   - Added video/mp4 to YouTube supported MIME types
 29496: ChannelsGet now filters out channels that are not authorised. Added a space before the node URL on status updates. Extended unit tests to check behaviour for non-Admin users.
 29513: Adds specific http client libraries to prevent the mac falling back to it's buggy default implementation (which, e.g. doesn't send Content-Length headers if the content length is zero). Required for Flickr support (their publish API requires both a content length header and zero length content. It returns a 411 error using the default Mac libs).
 29534: Fixed PublishingEventsGet REST method. ChannelService getChannels() methods now support filtering by publish permissions.
