I have just committed a change to wx.c and database.h that should fix the
transmission of incorrect rain rates by Xastir when using Davis or LaCrosse
weather stations.

Rather than modifying the db2aprs programs (Davis Meteo and Lacrosse), I have
taken the approach that since db2aprs (and the Lacrosse version) already 
provides 24-hour and last-hour rain data, that Xastir should not overwrite
these.  Further, I have set the code up so that Davis APRS Data Logger
rain rates are used directly, instead of being overwritten with incorrectly
computed values.  

I have already sent this change in private email to Mike, but ask that all
Xastir users that have weather stations do a CVS update and check that I have
not broken Xastir's handling of their own weather station (this change is
supposed to have ZERO impact on stations other than Davis or Lacrosse).

Mike, you needn't bother applying the patch I sent you if you just do a 
CVS update, as I already committed the change.
