[OSGeoLive] QuickStarts - question about updating the version number

[Felicity Brand]

Hi Cameron and all,

Seth G (geographika) and I have been chatting about the version number
in the docs and I want to clarify it.

At the top of each QuickStart we have a version number. We originally
thought because we'd checked the doc against OSGeoLive 13.0 that we
should update it to 13.0.

We read the trac wiki guide that explains it, and now we think that we
should leave it untouched because it's actually meant to state that
the doc is valid from version x onwards.

:Version: <OSGeoLive version from which this documentation is valid>

And I wonder if it's actually a variable because the guide describes
version as "Project's version defined into projects_info.csv"

It's ambiguous to me. Can you please clarify?

Thanks
Felicity
