[PATCH 0/2] Add groundwork for semantic versioning

[Finucane, Stephen]

> This series adds two crucial changes to the projects documentation.
> 
> The main focus of this series is to add some adminstrator-focused
> documentation to provide instruction on the upgrading Patchwork along
> with an overview of the changes between releases. Given that future
> releases make changes to the database and UI, it is important that we
> put in this groundwork now.
> 
> In addition, since we're now using GitHub as the primary resource for
> patchwork sources we need to update this documentation.
> 
> This documentation is top-level files similar to those found in every
> GNU project. It is not necessary to publish this information on
> readthedocs hence the use of Markdown.
> 
> I will be creating the appropriate tags once this is approved.

Would appreciate reviews on this. Anyone?
