WY/MT: US212 AltRouteNames on wrong route

[yakra]

During usanp activation, when WY US212Yel was deleted, its AltRouteNames were added to MT NEntRd rather than to WY NEEntRd the next line down.
The old WY US212Yel, which originally had the US212_W AltRouteName, corresponds to the current WY NEEntRd.

This causes an AltRouteName collision in MT: usanp is processed after usaus, and mt.nentrd "steals" MT US212_W in the route hash table from MT US212Coo, the proper route for that .list name.

usanp.csv:
usanp;MT;NEntRd;;;North Entrance Road, Yellowstone NP;mt.nentrd;US212Yel,US212_W
usanp;WY;NEEntRd;;;Northeast Entrance Road, Yellowstone NP;wy.neentrd;
->
usanp;MT;NEntRd;;;North Entrance Road, Yellowstone NP;mt.nentrd;
usanp;WY;NEEntRd;;;Northeast Entrance Road, Yellowstone NP;wy.neentrd;US212Yel,US212_W

I've fixed this and will pull it in shortly.
