The crash was cased by massive Mat objects leak in NativeCameraView class.

EMBED_CUDA and FORCE_EMBED_OPENCV flags added to cmake macro add_android_project;
INSTALL_CUDA_LIBRARIES option added to OpenCV.mk
opencv_dynamicuda library installation with enabled OPENCV_INSTALL_MODULES flag fixed;
CUDA initialization apportunity added to OpenCVLoader.initDebug();
Tutorial-4-CUDA sample reimplemented with static OpenCV and CUDA initialization.

CV_CAP_PROP_SUPPORTED_PREVIEW_SIZES_STRING property is not supported
by all VideoCapture backends. Some backends can return 0.0 or -1.0.

New version of Java wrappers' generator uses different wrappers for VideoCapture
on Android and desktop to prevent binary compatibility issues.

It increases performance on some devices like Nexus4.
Target Android SDK version increased up to 14.

Now the features2d class wrappers use composition instead of inheritance.

- enable auto-wrap of VideoCapture;
- minor refactoring of generated code templates.

OpenCV Version 2.4.6;
OpenCV Manager Version 2.8;
Doc fixes.
