To speed up rebuilds, define the NDK_CCACHE environment or CMake variable
to the path to your ccache binary. When declared, the android.cmake.toolchain
automatically uses CCache when compiling any C/C++ source file. For example:

export NDK_CCACHE=ccache

Previously the generator always uses hardcoded list of modules.
This fix replaces hardcoded list with actual set of modules coming from cmake.

fixed MCVC warnings

added texture_binder

All the functions from it are moved to the header
opencv2/photo/photo.hpp

added some sample description

modified facedetect to properly display very oblong objects and optionally flip image horizontally (for profile face detection). Added LBP cascades by Attila Novak for profile face detection and silverware detection (those are results of GSoC 2012)
