Improvements to the handwriting detection.

Bug fixes.

- Added Undo until solvable. Here is how it works: when a hint shows a error in the position, you can use this new button to go back to before the first error was made. As often the case, one error leads to another and by the time you notice it, it's easier to go back to a good state rather than trying to fix the position. - It is now allowed to write over a number to replace it (except for the given numbers of course). The app is not going to warn you though if you accidentally change an already solved cell so look out for that. - The ink color is now a little lighter to help make the given numbers stand out.
