1. Remove 'db level' from objectlib (this belongs to the app!)2. change ScreenPlay's 'mObject' to be an ObjectType.
Move PreRender to objectlib.This code is now shared betweeen the Rubik and Tutorial activities.
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.
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'
