#1363382 by sw3b: Fixed Error on viewing single activity and the date field do not reflect permission.

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

Fixed the pager so it works for all ajax calls to fetch older messages. This means separation of the normal page callback that would not return ajax anymore.

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

Fixed menu title and callbacks for singleactivity and viewsactivity. They did not need to appear in the administration. Also changed configuration and defaults for the two previous mentioned so the page_disabled property makes sense.

Fixed the ctools stream configuration object settings variable. Then deny singleactiivty is a fact. SingleHeartbeat is renamed to singleactivity.

Changed permissions do DX7.
Added buttons and prepared for attachments.

Added single message activity. Purpose is to display a single message when linked to it from everywhere, such as mail notifications, user-to-user communication, etc ...

- Added a new feature so administrators can set streams on profile pages. Select which stream you want to expose to the drupal user profile pages and that's that.
Lots of refactoring has been done but it was planned. We now can configure EVERYTHING and override everything we want.
- Fixed a bug at saving the configuration settings of a stream. The bug was in fetching the maximum number of messages to load. Saving did it, but the admin overview took a hardcoded default value.

Ran heartbeat through coder to make it notice free and follow every strict drupal convention. Succeeded.
