Resizable pickup cards / Count hidden cards

[albinantti]

The pickup view currently only allows a certain amount of order cards to be displayed (16 in progress and 8 ready for me). This caused minor confusion at times, since a few people during the river rafting festival didn't realize their order was "below" the view port and asked about it.

We should implement a "x more cards" card as the last one visible, or make them resizable so that more ready orders can be shown.
