0.48.0 - Improvements detecting a potential solution

[meikpiep]

Added

• The detection of a possible solution to show a button to check this solution was enhanced: It
  supports cells without a possible filled in if this cell is in a row or column which was already
  filled out completely except this single cell. Then, the remaining value of the row or column will
  be checked. (Reported by @spanezz)
• The upcoming Human difficulty algorithm now detects more variants of nishio (that is solving by
  propagating possible values) when calculating the difficulty of a grid. Currently only available
  in debug builds.

Changed

• At app start, all saved grids are tested if they need a migration to a newer save game format
  until now. This gets executed in the background to speed up app startup.
