We don't need them for the end user runtime and this speeds up the
install quite a bit when installing from the full tarball.
Devs will need to run `composer install` to run unit tests locally
but that's about it.
Currently the installer fails when using a github tarball that comes without a .git folder (https://github.com/LibreTime/libretime/issues/47#issuecomment-285365745).
With this change build.sh only executes git if a .git folder is detected. It uses the name of the downloaded folder as part of the version string if a tarball is used.
I plan on releasing travis-ci built tarballs that contain the tagged version (once we have one) and also have a pre-downloaded composer vendor folder. Those will already contain a VERSION file as well and this change already contains the setup needed for that.
