Do not allow more than 15 characters in the NAME.
Bugfix in DialogSetName - before it would not dim the OK button initially
Fix clickable links in the About dialog.
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
Lots of bugfixes.
Move to AndroidX, target API level 29.
Improve the Effects Dialog so it looks good on 'thin' screens ( 720x1440 )
(Hopefully) make the Dialogs NOT disappear on clicks outside (previously this wasn't working on Android 9).Lower API requirements to 21.
Each object size now has its own number of levels (not always 18!)
Reorganize UI of the Play state.
Progress with the 3x3x3 Solver.
More support for the 3x3x3 Solver: more of the actual 3x3x3 solver mechanism.
