Preview in nonogram solver

Now online nonogram solver has preview window.
Small, but very useful feature to simplify solving process and do it more enjoyable. :)
As usual, check at updated digizzle site.

Update of the site

Main improvement - now you can lock an empty cell in a nonogram (it's convenient if you sure the cell is empty). Hold the Shift key pressed while clicking the cell to lock it.
Two new nonograms added.

Beta version of the site

Finally, I upload beta version of the new website, where you can play nonograms online. If you find bugs - please, let me know.

Gameplay will be improved, currently it's just a proof-of-concept.

Currently, there are only two puzzles at the site, and the first one is just a test. :)
New puzzles will be added from time to time.
