group based molle accessories for zed soldiers

fow a while now I've had the idea of moving molle accessories to a
"loadout" system; really just move them from a list with probabilities
that repeats itself to a manual groups of items a "loadout" in my mind

extend how molle accessories spawn, more stuff, more complex grouping
and try to spawn them logically i.e. one of each category,
containers/storage, utility and combat accessories
