Provide a way for tracking if user acted on a recommendation

[Łukasz Czyżykowski]

There should be a way of tracking if given recommendation was acted by user, that is, if recommended application was actually installed.

This would require implementation on both server and client. The server side needs to provide an api for client to call when recommendation caused user to install an aplication.

The client side needs to track which recommendation (if any) was displayed before user installed given application.

This requires tracking user behaviour, but it's part of getting feedback of the quality of recommendations we are computing. At the point where this call will be used, user already had opted in into recommendation system.

[Anthony Lenton (elachuni)]

This will involve a new api call. The API call should be authenticated, and take two arguments (besides the implicit authenticated user):
- The package name
- a (shortish, freeform) "action" string to explain what was done with the package. Some possible actions would be "installed", "clicked on rec", "viewed", "uninstalled". I'd suggest keeping the length down to < 20 chars.

[Anthony Lenton (elachuni)]

Two options for the url:
 - Replace the /feedback/ API call, that's currently unused by the client.
 - Add a new /implicit_feedback/ API call, and leave the other one for now, we can remove it down the road.

Leaving currently at fix committed till the usc frontend code it in place to trial it fully.

    - startup time improvements
  * lp:~mvo/software-center/adt-you-make-my-life-hard:
    - updates to make the tests run as user
  * debian/tests/run-tests, run-tests.sh:
    - ensure there is a apt-xapian-index available as this is not
      automatically created in the ADT test VM environment
    - fail to run the tests if there is no apt-xapian-index
  * lp:~mvo/software-center/lp1045330:
    - return an empty string if there is no price instead
      of the "None" string and add test (LP: #1045330)
  * lp:~mvo/software-center/lp1044900:
    - add local "trans" var to fix crash (LP: #1044900)

  * lp:~aaronp/software-center/review-refactor:
    - This branch simply converts the existing callbacks for retrieval
      of review data and submission/deletion/modification of reviews
      to GObject signals (courtesy of mvo) which makes it more consistent
      with the rest of the code

  [ Gary Lasker ]
  * lp:~gary-lasker/software-center/recommended-installed-feedback:
    - signal the recommender service when a recommended item has been
      successfully installed, refactor and clean up surrounding code,
