Task-number: QT3DS-3592

    
    Replace presentationReady use with presentationLoaded due to changes in
    OpenGL RT signaling. presentationReady indicates that the presentation is
    fully built up (and visible), which is not the case in HomeAutomation
    loader-based code.

to make it work fine with the new vec4 color type. Also optimized the
frag shader a bit by removing unnecessary calculations.

Also added FPS counter and possibility to use either
RT1 or RT2.

...to help Android deployment.

Removed forced mesh revision from *.uip file to allow using the
optimized meshes.

This is a partly revert of 8e8142cb as the car was not shown
correctly after that change (I have no idea why).

Having the needle slightly transparent is causing sorting issues and
therefore causing the needles to be obfuscated once they reach a certain
point.

The existing values were causing the needed to jump because the
root values couldn't be calculated. This is a bug in Qt3D, but
we can't fix that before the next patch release.

Remove TennisGame demo since 2.0 doesn't support all he behavior
functionality needed by it.

This is currently required by the new runtime.

Use runtime2 and correct surface format.
