Find a better way of listing board positions on the internal member page

[Gunvor4]

So far, the board positions are listed in the field 'role' on the internal members page. This is a text field (an UnlimitedCharField on the Member model), and in addition to current board positions, it also lists previous roles. We would like a more structured way of listing board positions, and we would like some way of separating current and past positions.
