Title: Add to documents requirement of installing zlib1g-dev for installing kivy development version

For some version of Ubuntu(e.g. for 13.04) it necessary to install zlib1g-dev, as without it error while compilation may occur(can't find zlib.h). I found that while googling but I think it would be good to have it in instruction to not disappoint developers.
