Dan Albert cce9592ac8 Use task priorities from aircraft yamls.
Preferred aircraft per task are now determined by a ranking of weights
stored in the aircraft yaml files. To aid in visualizing the priorities
across aircraft, Liberation can be run with the argument
dump-task-priorities to dump a yaml file in Saved
Games/DCS/Liberation/Debug/priorities.yaml, which will show each task
along with priority sorted aircraft and their weights.

The current weights in the data were exported from the existing lists,
where each position from the bottom of the list was worth 10 (to allow
some games for less shuffling later).
