updated antibiotic dosing sheets by adding new vancomycin dosing equation for 24h infusions after a 1g load. This is taken from Int J Antimicrob Agents, 2011, 37, 75-77, Jeurissen2011.
Merge branch 'master' of git://github.com/agregson/fitzmed

I tried to push changes of the antibiotic dosing sheet without ensuring that I was up to date locally with the remote. Somehow I was not up to date locally.
