Set up possible deliverables for the Sprint

[lubianat]

Note down all kinds of deliverables that can be done at the sprint.

The deliverables can be added as new issues, and they will go directly to KanBan.

This will be an "in-progress issue" until the end of sprint.

Goals can be techy (for example developing a prototype of a Graphic User Interface) or conceptual (ideas for features, possibilities of gamification, applications and so on).

For example, if we have someone good at design, it would be nice to come up with a preliminary logo.

Each deliverable would, ideally, be attainable during the sprint.
