[Xastir] Rainfall

[Ray Wells]

Kurt,

I did try also keeping Humidity but it failed when compiling and I 
didn't even bother to see why.

As I stated up front, I'm not a programmer, but that won't stop me again 
trying to also display humidity, when time permits or, my desire to beat 
the problem wins out.
