Portfolios API

In response to a feature request, the back-end of the portfolios feature has been implemented. This allows the creation of a collection of images (like a virtual folder) that can be viewed together, altered together (e.g. resized to the same dimensions) and downloaded with or without changes as a single zip file.

There is a new rather basic web page for viewing a portfolio, but otherwise the front-end administration UI does not yet support the creation and management of portfolios.

For more information and a technical description of this new feature, see the portfolios specification. For examples of how to use the new API, see the API user guide.

This change has been fully integrated into the ongoing python3 branch, which will soon be released as QIS v3.0.
