Small Changes To Prepare Pull #589 For Merge

I think this makes all of the remaining changes @saivann and I mentioned on https://github.com/bitcoin/bitcoin.org/pull/589#issuecomment-57712688 .  Feel free to rebase it in.  

I reviewed the diff of all the changes with this patch applied, and everything LGTM.  I also built the site and ran the tests, and no problems were found.  Thanks again for all your edits!
