Added VideoCapture class, which allow to get a QImage from individual frames of QCamera. Also an example is given in 'main.cpp'

Notes:
  1. in order to make it work in Android, it is needed to bind QCamera in C++ from QML
  2. I need a better interface to make it work with OpenCV in a transparent way
  3. Probably the name of the class will change :P
OpenCV image processing example using Qt for reading (from the camera) and displaying the image. Note: I need to move this code somewhere else
QML camera
Merge branch 'master'
Somehow needed to add 'libopencv_java.so' to make it work compile (I should fixed in another way). The error I was getting was:

[...]/OpenCV-2.4.7-android-sdk/sdk/native/libs/armeabi-v7a//libopencv_imgproc.a(templmatch.cpp.o):templmatch.cpp:function cv::crossCorr(cv::Mat const&, cv::Mat const&, cv::Mat&, cv::Size_<int>, int, cv::Point_<int>, double, int): error: undefined reference to 'cv::getOptimalDFTSize(int)'

Note: I have symbolic links to the .so libraries inside the Qt5 folder (Qt5.2.0/5.2.0-beta1/android_armv7/lib)
