Dsf-MV-Integration: Proof of concept

The following changes allow you to:

1) Compile your CDT and Trace-compass plugins the same workspace, using the .target file
2) The proof of concept can be exercised by
      a) opening a kernel trace with trace-compass
      b) open the "visualizer" view
      c) from the visualizer you should see 1cpu, 2 cores 
      d) from the visualizer context menu, Enable load monitor
      c) The load meters should now reflect the cpu load for the duration of the trace

I think it's good enough for a proof of concept.

Next, 
* Visualize load on the time selected by user over the trace views
* Discuss and improve API
* Proper closing 
* etc..
