Magic Cube

Rename Meshes.

Fix: nwo we need to explicitly set mesh center to negative Z if we want to GLOW a flat object.

Fix for Samsung Android 5

Fix for one bug seen in Firebase and additional debugging for another.

Finally fix the Dino's 'isSolved()' - Dino can be mirrored and then it is also solved!

Update dmesh'es to 'proper' (i.e. with centers) version 2.

Update all the dmeshes to versions 2.

Fix detecting if an Object is solved. Before, the generic Cubit.thereIsNoVisibleDifference(0 would not work correctly in case of the Dino.

Adjust randomizing new rotations so that:

1) it works for basicAngle=5 (Megaminx) (so now basicAngle=2,3,4,5 supported)
2) it leaves the decision as to what can be the next rotation to the Object class, as in case of certain Objects (the Dino, or the Helicopter, the Megaminx) the next rotation doesn't have to 'intersect' the old rotation always when oldRotAxis != newRotAxis (that's so simple only in case of the Cube and - only partly - the Pyraminx!)
