[hibernate-dev] Updated build script using git clone

[Sanne Grinovero]

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
