[Xastir-dev] Weather Validation Patch

[Clay Jackson]

I finally got around to modifying Xastir (1.9.4 stable) so that it would not repeatedly transmit weather data from a "broken" or down interface - so, here's my first attempt at a contribution.  Do with it as you will :-)  It's a work in progress; but I wanted to get what I think is a stable version out for folks to look at.

I also included some code that computes how "old" the latest weather record is - my goal is to have put a "timing" bar in that will allow the user to select how old you want weather data to be before it's considered "too old" to be useful (i.e., transmitted).
