Magic Cube

1. Remove 'db level' from objectlib (this belongs to the app!)
2. change ScreenPlay's 'mObject' to be an ObjectType.

Reename ObjectList to a more logical ObjectType.

Simplify ObjectList: now there's just one object per size.

Remove all files that have been separated into a new library 'objectlib'

Prepare the 'objectlib' package to be separated into a library module

Refactoring: split the 'objects' package into two, 'objects' and 'objectlib'.
The point: we're going to need to move the 'objectlib' stuff into its own library module, and that's because we're going to create a new app module which needs access to it.

Cube Control: step 2.

Rename 'state' to 'screen'

- report the Graphics driver's Renderer and Version.
- new Diamond, Skewb2 and Skewb3 meshes.

Improve the Ivy mesh.

Lots of changes:

1) new 'info' button (not working yet)
2) make all dialogs modal; rework the way the Pattern Dialog appears.

Bigger 'OK' button in Dialogs.

1) report all solved levels to Analytics
2) automatically dismiss the NewRecord and Solved dialogs when one backs from the Done state.

Rename some classes.

Rename some classes.

Make it so that the Navigation Bar does not re-appear when we pop up a DialogFragment.

Now there's noly 1 case when it still reappears: it's when we pop up a PopupWindow.

Solving time - display it more accurately.

Improvements to the UI - make it proportional regardless of the physical screen size. (Part 6 - next 5 Dialogs)

Finally solve the bug on Samsung Android 9 and 10 phones that the Dialogs Main & patterns wouldn't be modeless: move the setting of this flag earlier, to the 'onCreateDialog()' function.

Minor.

Lots of bugfixes.

Move to AndroidX, target API level 29.

(Hopefully) make the Dialogs NOT disappear on clicks outside (previously this wasn't working on Android 9).
Lower API requirements to 21.

More support for the 3x3x3 Solver: more of the actual 3x3x3 solver mechanism.
