Fix pricing

[odinuge]

We currently have two prices per event; one for members of Abakus and one for others (lets call them guests).

The frontend only use the Abakus-price, and members not in the abakus-group ends up with the sum 0, unable to pay. We should consider changing the behavior, to make it more flexible (eg. for Vaargalla where alumni should pay more...).

Maybe:

• Add one price per pool
