3 bugs fix: 

Hi,

I was trying to use this great addin but it doesnot work on my computer.

I fixed the 3 main bugs i have found:
- VSEventsHandler doesnot detects when a solution was opened or closed (event was not call)
http://stackoverflow.com/questions/5405167/dte2-events-dont-fire
- If UnitTests projects are in sub "virtual directory" in the solution, they are not detected.
- When User doubleclick on the ResultsControl on an unexisting constructor ".ctor" the addin crash
If you have any questions don't hesitate.
