This commit breaks compatibility with Qt 5.4 and earlier versions. It removes the
temporary QObject based TypedArrays and moves the code to use the native
QV4::TypedArray support in Qt 5.5. This allows the implementation now to also
add support for compressed textures and support all getParameter() values.

All QObject output values are now wrapped in to QJSValues and
input QObject values are treated as QJSValues. Id property removed
from the Program3D object as that shouldn't be exposed to the JS side.

All JavaScript visible objects are now based on QQmlPropertyMap so that libraries and other users can add dynamic properties to the objects like they do in many cases. Also fixed textured cube example to respect devicePixelRatio.
