Thanks to Dean Groe's testing efforts, I've concluded that Meteo does not 
in fact store in its database the quantity that Xastir considers "Total Rain"
but only "total rain so far today" --- rendering the change I recently made
to db2APRS unnecessary and in fact incorrect.   I've reverted the code change
and now db2APRS is once again producing completely standard APRS-spec wx 
reports, with only the three normal rain data: 1-hour, 24-hour, and since-
midnight.

Xastir will now display a blank box for the "Total Rain" information in 
"Own Weather Data", as there is no way to recover that information from what
we have,  but everything else will be right.  Prior to my first hack on this
part of the code, *ALL* of the rain data was behaving incorrectly, so at
least there has been some positive change over the last few weeks.

I have left in place my change to the LaCrosse "open2300db2APRS" program, 
because open2300 *DOES* put "Total Rain" into the database, and this program
is able to pass that information on to Xastir.

Thanks, Dean, for helping to verify whether or not the changed code worked.
Pity it didn't.
