@danoli3 I want your opinion on this one as it changes install scripts
I've noticed if we install one package at a time it spends some time on "reading database" so if we convert this to oneliner it can shave off about 2 minutes for installing dependencies.
Do you see any downside?
this is the specific change:

- installPackages ${PACKAGES}
+ apt-get -y -qq install ${PACKAGES}

This is finally ready to go @ofTheo.
Don't mind the number of commits I've splitted this PR in other ones.
