Some bug fixes and minor improvements / New 'Active Run View'
Fix project selection bug in navigator

Fixed a bug with project selection when the DS project navigator was
closed and reopened because even when no items were selected the
previously selected projects were still cached in the Activator. Now
when disposing the navigator selected projects are properly cleared out.

Use StatusManager for some errors

Added more details in some exceptions using the StatusManager.

Small changes in ResultsView: fixed a bug when the results.ser file was
not found and the update process was not interrupted causing another
unnecessary message dialog to pop up.
