Updates to the Walk-in Cooler

See post #152 on the homebrewtalk.com thread for an important update I made to the cooler *after* the article for Zymurgy was written. After having a moisture problem with a leaking keg, I decided to add small 12 volt fans that run 24/7 in the front grill of the AC to constantly draw "warmer than freezing" air over the AC coils. This has completely solved all moisture problems.
