Document proper way of installation so users will recieve hotfixes
In our installation instructions we say:
On your **provisioning machine**, clone the OpenAppStack git repository
and checkout the latest tagged version (currently ``0.5.0``):
$ git clone -b 0.5.0 https://open.greenhost.net/openappstack/openappstack.git
But with cloning a tag users won't recieve hotfixes for the release branch.
