20000229: UKMET grid files

James,

This stinks of a problem with the pqing NOAAport ingestor
when looking for the GRIB start "GR" and finding the GR in EGRR.
As a result, the products were flagged as not having the appropriate
WMO GRIB format.

I looked at the IDD ingestion logs and found that pqing is dumping many of
the ukmet grids, whereas my NOAAport feed here which doen't use the ingestor 
does receive those products. I believe that Glenn Davis fixed the GR problem 
last year-
but his work may not have gotten into the current release after his death.

I'll store the EGRR grids from my receiver tonight and see if I can
determine where in pqing the IDD grids are getting lost.
