Clear tracked object when data sources are removed.
Material support for DynamicPolyline

Originally, we hardcoded DynamicPolyline to always us a PolylineOutline material type because we did not support general materials in CZML.  Now that the DynamicScene and CZML processing are decoupled, the lack of CZML support for it doesn't matter.  This allows users to use any Material we support in DynamicScene that also supports polylines (currently just ColorMaterialProperty and PolylineOutlineMaterialProperty but others are trivial to add).

Use new events to detect when a trackedObject has been removed and fly to home view when it happens.
Disable unused local variable warning in Eclipse.

The latest version of Elipse claims ther are over 100 unread local variables in our code base, 0 of them appear to be accurate.  Since the warning is now useless, we should ignore it.
