Release of XStudio 1.6a6

This has been released yesterday.

It includes many bug fixes as well as the major new feature that add to your SUT and campaign tree a "Quality" column indicating an index of quality of the SUT.

Details of the 1.6a6 add'ins:

   * Quality metrics on the SUT tree
   * Quality metrics on the campaign tree
   * New unified colors for progress bars
   * New areas selector on the left-hand side
   * Agent not responding timeout set to 30 seconds
   * Bug-fixes:
     - Incorrect UI indicators when a session is queued too long on
       an agent
     - Session not starting when queued more than 15 minutes on a remote
       agent busy with some other sessions
     - Refresh the progress at the end of a session execution
     - Too many stats recorded: XStudio frozen when selecting the integrated
       bug-tracking root node
     - Wrong color returned for the graph in the iPhone/iPad app.
     - Incorrect statistics reported in email notifications when re-executing
       a manual session
     - Exception while selecting some folder in the Campaign's content tab in
       the upper test tree
     - Main tree refresh issues (ordering) if defect tree is not in the user
       profile
     - Exception and inconsistent behaviour when modifying sprints and backlogs
       (due to velocity chart refresh)
     - Incorrect Bamboo report generated in case of test failure with messages
       (typo in the CDATA opening tag)
     - No more timeout on the sessions that have been queued for a long time.
       The 30s timeout for "not responding agents" now applies only starting
       from the point where the session has really been started by (at least)
       one agent.
     - Wrong background in the campaign tree in some cells
     - Force the stop even when a session did not really started (in ARMED
       state)
     - setCampaignSessionAgentStatus() called only the first time
     - Error while trying t get the ascending/descending icons
     - "generate spec" vs "generate test" button depending on if the
       specifications are enabled in the PLC
     - Coverage label different in the form depending on if the specifications
       are enabled in the PLC
     - Generate specifications does not update coverage on the requirement if
       necessary
     - Generate tests does not update coverage on the requirement if necessary
     - Same width on progress bars in the same tree
     - Wrong new SQL query to retrieve latest results (for quality)

Enjoy!
