Magic Cube

Introduce abstract 4,6,8 adn 12 classes.

Move the Movement class from ObjectList to individual object classes.

Realize that the Movements of Rex, Redi, Dino and the Skewbs are all identical and convert those 4 classes into one MovementCornerTwisting.

Make computing the offset in the Movement class more correct. From now on, in the center of the face the offset if always 0 regardless of the axis.
Before it would always assume that we can add DIST2D to the offset which is originated at the center of the face and this way get an offset which spans from 0 to height of the face. This is not always true - conterexample: half of the triangluar faces of an octahedron which are 'upside down'

Move actual solving the object to PreRender.

(before we had a 'solveObejct()' in preRender already, but that one just starts the Solve Effect!)

Abstract out some methods from the Movement classes. only two remain now: rowFromOffset and enabledAxis.

Make the Kilo and Megaminxes standard size (dodecahedron size=3,5, i.e. equal to numLayers so that DIST2D and DIST3D are standard)

Make the Ultimate standard size (dodecahedron size=2, i.e. equal to numLayers so that DIST2D and DIST3D are standard)

Make the Skewbs standard size (cube size=2,3, i.e. equal to numLayers so that DIST2D and DIST3D are standard)

Make Rex standard size (cube size=3, i.e. equal to numLayers so that DIST2D and DIST3D are standard)

Make Jing standard size (tetra size=2, i.e. equal to numLayers so that DIST2D and DIST3D are standard)

Make Ivy standard size (cube size=2, i.e. equal to numLayers so that DIST2D and DIST3D are standard)

Make Helicopter standard size (cube size=3, i.e. equal to numLayers so that DIST2D and DIST3D are standard)

On second thought, come back to Vector. The problem: before we had the potentially blocking function 'effectFinished' inside our synchronized block.

1) add missing call to BlockController.onPause() / onResume() to the Tutorial activity
2) rearrange BlockController's error reporting to make the case where the MessageSender thread has died separate
3) in such case, resurrect the thread
4) simplify and harden the EffectMessageSender

Correct height of the tutorial dialog.

Up version to 1.8.6

Add Mirror 2x2 tutorials.

Increase NODE_RATIO, i.e. the height/width ratio of the DistortedNode behind the object (before with 1.4, if one scrambled the Mirror Cube and made it the largest possible, corners were cut off form the top and bottom)

Mirror Cubes: re-enable meshes; update meshes.

Mirror Cubes: make them still more off-center.
