Big refactoring to have heartbeat activity as a complete entity. Also fixed a bug: #1284376 by Sylense: Fixed Overriding activitycomments plugin breaks comments.

Refactored the setting for the profile page path to be consistent with the normal path. Leaving empty and full control over the path. Validation check should be added to avoid existing paths (E.g. conflict with other activity modules).

#1250324 by solomonrothman: Added Alpha version of shout box released for D7, What can we do to make it work with heartbeat?.

Removed complete translation table and the system to hold an original tuaid. We don't need that imo.

Issue #1175716 by morningtime: Added Comments not shown after page refresh when the node comment is unpublished.

Issue #1235620 by solomonrothman: Remove user activity from user relationships activity block/page?.

Issue #1215766 by solomonrothman: Insert Thumbnail Image from Content Type into User Feed- Almost there just need it not to strip the img src tag.

Fixed a bug when cloning heartbeat streams. Added a field real_class to holds the real class name from the original streams. Update.php needs to run.

Added relationsactivity stream with a flag_friend default implementation in the hook_heartbeat_related_uids.

fixed json modal to delete a heartbeat comment + fixed #1122258: Upgrade from prevoius dev version gives fatal errors - Object of class stdClass.
