Improved puzzle editing.

We have spent the last couple days improving the puzzle edit process. Most of what has changed it behind the scenes and most people won't even notice. But some is up front where you can see the change.

Mainly we cleaned up the way editing happens. As you change fields like the title, artist or brand, we do a quick check to make things more uniform. We had been doing most of this behind the scenes when the save happened. But now it happens as you move from field to field so if your text needs to be altered, you will get a preview before the save actually happens.
