[LDM #WBE-759234]: RUC questions

David,

The grid #236 40km data on noaaport are sent at 50mb intervals. 
The grids on the NWS ftp server are at 25mb intervals, but we don't send them
on CONDUIT since they are duplicates of the 20km grids already in CONDUIT.


for the grid 252 problem, change the pqact.conf pattern to:
# Grid #252 (20km) grib2:       prod/ruc2a.*grib2
CONDUIT prod/ruc2a.*grb20.*grib2

Turns out the old pattern matches both the #211 and #252 products since NCEP 
added
grib2 versions of the 80km grids. Adding that substring grb20 in the above 
ensures that
you are getting the 20km grid.
