Magic Cube

Move the main app to the 'J1M1' object creation mode, i.e. create them from the Json files and using the Dmesh fiels as well.

Make it possible for any app descending from the 'objectlib' to use any of the J0M0, J0M1, J1M0, J1M1 modes.

Fix for a rare crash.

Standarize icon naming scheme.

Minor

Use the latest objectlib

Correct the 'solved' icons in the Play popup.

Correction

1. Do not restore object scrambling if we freshly upgraded from some version older than 1.9.0
2. Bugfix for a recently introduced crasher in the Play screen.

Create the 3 Popups only on first button click - this time we can have the final screen dimensions (and also it starts faster ) Before we weree getting the screen size from before hiding navigation bars, which made the height smaller, which made the number of obejcts and levels in the popups sometimes too small!

Progress with cuboids.
