quickly corrected the previous refactoring of features2d: moved from set(SOME_PROP, val) to setSomeProp(val)

OpenCV with the refactored features2d compiles! contrib is broken for now; the tests are not tried yet

Implemented as a new optional parameter for
the constructor of the ORB detector. The
change of this parameter has been included
in the orb unit test.

1) Clean-up from the unused code
2) Remove of SURF extraction method
3) Enabled threading for KAZE extraction
4) Exposed new properties for runtime configuration

Added the defaultNorm() method to the DescriptorExtractor class. This method returns the default norm type for each descriptor type. The tests and C/C++ samples were updated to get the norm type directly from the DescriptorExtractor inherited classes.

This was reported in feature report #2182 (http://code.opencv.org/issues/2182). It will make it possible to get the norm type usually applied matching method for each descriptor, instead of passing it manually.
