Station view also sorted by state.

This makes the arrived/finished groups appear last in the list.
Improved station sorting.

Groups which have arrived at the station come first. Next show the "unknown"
(not yet arrived), and put the "finished" groups last.

This should minimize the need to scroll too far down.
Better alignment of form icons with fields.
Removed "step" value for game scored.

It was only used for testing and somehow slipped through into the code base.
Slighly better group display. Still needs work.
