Show timer and time to complete

[nitrocode]

Great app. Love that there is an open source version of hanjie.

Would you be open to adding a visible timer while solving the puzzle and then show the amount of time it took to solve it? This would help show me how much time I'm spending on the game and help me gauge if I should change the difficulty. Thank you!
