Now the features2d class wrappers use composition instead of inheritance.

Typo breaks debug build for Android platform.

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

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

'dst' should be treated as an input arg (epilog not needed)

Simple set of the camera index to allow the user to change it after the object has been initialized.

A modification of the JavaCameraView is needed to avoid a crash when the
app is exited. It is a good practice to remove the callback after the
stopPreview method.

Also, removed the one from modules/python/src2/cv.py and cleared its
executable bit, since it's not a script.

Front/Back camera constants' values changed;
Additional camera facing check added for JavaCameraView.

* Drop some low level API
* Remove outdated overloads
* Utilize Input/OutputArray

OpenCV Manager verison incremeneted;
Docs and tests updated accordingly;
COnstant for Manager initialization added.
