WeatherPM

This adds programmer art-esc textures for ProtoManly’s weather. I am not quite sure _why_ anyone would want this, but maybe if you use something like Programmer Art+ or the Programmer Art Continuation Project, this might be useful to blend in the textures. This will (hopefully) be updated to support any changes with PMWeather 0.15-alpha.

This also brings back the old Weather2 siren sound!

Weather2, as i have used some of their textures. _Please contact me if you would like these to be replaced (even though i am very likely to in the future anyway)_
