Magic Cube

Convert the theme to be a MaterialTheme and the TransparentImageButton to be a MaterialButton - the first forced by the second, and the second because a MaterialButton gives us control over the location of the icon in top of it. We need that because of the new 'solve/scramble' split-button in the lower right of the Play screen.

Fix the solver (after rearranging the faces of the cuboids)

Fix problems with TwistyObjectNode 'object scale' property.
Now this property is not part of the Node at all, but its initial value passed to the object in its constructor.

Bugfixes for crashes from Firebase.

Bugfix.

Add 7x7 tutorials.

Tutorials for the 6x6

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.

Remove ObjectType from a few moree places.

Simplify dependancies.

Remove dependancies on Firebase from objectlib.
Report such errors to the application via the Interface.

Progress with PuzzleTester app.

Fix for a rare crash.

new API to make is possible to adjust default scale factor in each TwistyObjectNode.
(and use it in Tutorials, where the object needs to be smaller)

Major change: separate the notion of a TwistyObject and its Node. Now,

1) the Node stays when we change objects (this makes transitions faster)
2) it's possible to just create an Object without adding it to the Screen (now app needs to explicitly create the Node and add it to its Screen itself)

Standarize icon naming scheme.

Minor

Use the latest objectlib

Correct the 'solved' icons in the Play popup.

Correction

Bump versionCode to 42 (forgotten before)

Fix a lint error.

Correct location of the keystore.

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.
