refactored the part where default message template can override and be reverted, deleted, ... with bitshifting as linux permission system

- 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.

- Added feature : add event on heartbeat comment to hook into. [d.o. issue , http://drupal.org/node/715694]

- Added privacy settings to opt in / out from message type display. From now each user can say he does not want to see pages posts in his streams.
- Also added the default actor object to the heartbeat activity object.  This object needed to have all the users releations to be check the message visibility.

Fixed a javascript issue.

- fixed hds to work with ds release
- added TODO
- bugfixes from issuequeue
- Added the query for friendlist>user relationships
- refactored comments
- altered the pager ajax callback

update hds fields as well with new formatters

Fixed a notice on admin templates edit page

Found and fixed a fix runtime notices
Refactored the javascript to poll newer messages. It very often gave an error as it did not find the most recent activity item.

Added a shout data type for rules within shouts. Changed the available tokens, so it has nothing to do with drupal comments anymore.
Changed the friendlist activity rule to hold the new tokens.
TODO: do the same for both way relationships.
TODO: do the same for user relationships module. I ll have to check first if the module defines a rules event where heartbeat can hook into
TODO: provide a user relationships example by implementing a UR hook to log the activity.

Fixed some notices and cleaned up code for node comments vs heartbeatcomments. The are handled the same way now.

Changed hds to keep up our work on display suite. Altered definitions of content_build_modes and ds_fields implementation.
Made some minor changes to the example, after being noticed of notices by simpletest module.

Altered friendlist_activity so that it takes the possibility to set your user relation api module to obtain relational activity

Improved heartbeat display suite and altered the template names! This was needed as in nd module. Else default template could not load anymore on some occasions it should have

Altered the default heartbeat commentlayout and example as well.
Changed default attachments storage
