Refactor RubikObject in preparation for creating RubikObjects from DownloadedObjects.
Remove 3 out of 4 object icons.
In the 'magic' app, ObjectType is now only used in RubikObject and RubikObjectList classes and nowhere else.This is a major step towards being able to download objects from an online repository.
Minor
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.
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.
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.
Improvements to the UI - make it proportional regardless of the physical screen size. (Part 7 - last 2 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.
Only 2 dialogs are modeless now: MAIN & PATTERNS
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.
