2. Add qt4 feature, which conflicts qt3. Qt3 must be now explicitly defined. QT4DIR must be defined (defaults to /usr/share/qt4, which works for debian)
3. Add checks for python modules and prettify boost checks.
4. Remove a lot of legacy code, so that the qt4 build avoids yade::serialization completely
5. Add live inspection and modification of arbitrary sequences, for a showcase see the Inspect button on the simulation tab (Body/Interaction inspection will be rather easy as well)
6. Add common handling of number arrays (Vector3, Matrix3, Quaternion)
7. Add to-python converters for vector<vector<string>> and list<string> (only needed in Dispatchers, avoids tome exceptions)
8. Rename OpenGLRenderingEngine to OpenGLRenderer
