Number spotlight

Version 1.46.0 includes a new spotlight feature for highlighting numbers. 9x9 puzzle generation has also been improved. All changes in detail:

• The new number spotlight feature makes it quick and easy to highlight numbers of the same value. The How To Use and Tips sections of the introduction have been updated to show how the feature works.
• 9x9 puzzles are now generated faster and the puzzles are more likely to involve advanced or expert complexity, when generated at these levels.
• An issue has been fixed where the finish button would sometimes turn active while there will still squares with pencil markings, even though not all blocks had been placed.
