I am providing difficulty for "blocks" tab from query string.
This required minimum change in current code and it will help explain concept of difficulty while introducing nonce for a block.
If you want then I can take this concept forward for all tabs.
I'd rather not do this as passing those arguments on the URL seems bumpy. I'd rather it as a hidden "feature" and if so, on all pages that use difficulty.
