[hibernate-dev] Updated build script using git clone

Hi all, I updated the build script which Emmanuel shared initially: https://gist.github.com/Sanne/789588 I now maintain an environment variable BUILD_COMMAND which is automatically set depending on the project I'm working on (among JAVA env, Maven versions, Maven options & all that stuff which is always different for some reason) That's what works best for me, I assume others are in the same boat. enjoy
