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!

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!)

Add the Dino dmesh file.

Fix the way we continue rotation: when rotating a layer, we need to be doing it with respect to the RotAxis which has been first casted to the touched face, and only then this casted one is casted to the surface of the screen.

Before we were casting the rotAxis directly to the screen without the intermediate casting to the face, which doesn't really work in case of the Dino: if the touched face is rotated away by quite a lot, the rotAxis is then completely counterintuitive.

Major progress with Dino; rotations (almost?) work now.
