Smallfixes

Fixed Gametime-overflow-bug.
Gametime is now displayed in days and hours too. (No zero-padding 2min is still 02:00)

Updated robotium-jar to 4.1

Fixed easy template bug by updating templates.
Generation shortcut is commented out as the idea behind it seems to be:
return always a sudoku from the identical easy to guess pattern that is just transformed.
(and I remember heiko saying there's no speed difference anyway)

changed version name from to old to upcoming

finished sudokus are now displayed with ✔ instead of gelöst/finished/resolé
(TODO in code)
