Fix and format 2011/zucker/README.md

There was a mistake in the try command where it would inject into the
image the previous command specifically because of !! - must escape
these even inside double quotes (there were three).

Typo fixes here and there.

Format fixes.

Unlike the others I did not add any additional links as I am almost out
of time for the day. I will look at this again another time as there
were a number of things that I think would be improved with links.

Fix author URL in README.md and winners.{csv,html}.
