* Adds the main features2d header to the parse list for the generator.
* Removes the manual definition of drawKeypoints and drawMatches since these are now included in the main header.
* Updates the generator to ignore SimpleBlobDetector, FlannBasedMatcher and DescriptorMatcher as these cause conflicts with the generator. This is okay since these were not previously included in the distribution anyway, so no harm is done.

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

Conflicts:
	modules/core/include/opencv2/core/cuda.hpp
	modules/cudacodec/src/thread.cpp

Now the features2d class wrappers use composition instead of inheritance.

e.g. <opencv2/core/core.hpp> become <opencv2/core.hpp>

Also renamed <opencv2/core/opengl_interop.hpp> to <opencv2/core/opengl.hpp>

Made all STL usages explicit to be able automatically find all usages of
particular class or function.

More granular build of Java API: it is now possible to build Java wrappers only for the subset of OpenCV modules

Added new tests written by Hussein Abdinoor; Added support for new classes in features2d and imgproc

JavaAPI: fixed typo; some constants are moved to private section; added tests for BruteForceMatcher-Hamming

Java API: added class pointer ret type support, CV_EXPORTS_AS(x) support for classes, vector<T> as ret type support, randu/randn params type changed to double
