Correct the 'solved' icons in the Play popup.
1. Remove 'db level' from objectlib (this belongs to the app!)2. change ScreenPlay's 'mObject' to be an ObjectType.
Move ObjectControl, the next big chunk of code, to objectlib.
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.
Fix the long-standing problem that putting app to the background would not stop the 'solving' counter.
Add a 'give up' dialog - if one made at least 10 moves when solving and presses a 'back' button, one needs to confirm.
Give visual indication when dragging is locked.
Abstract the part that controls the 'Locked' and 'Back Moves' buttons from the two activities: the main one and the tutorial one.This code had been duplicated there.
Cube Control: step 2.
Rename 'state' to 'screen'
