Added HKO Weather Warning Signal Symbols for future addition to nntp
Changes to some icons

Put less raindrops for Rainstorm red and amber, tsunami text white (and
made waves less lumpy but at this size, it is invisible)
Made these white
Made brown boulders white

Now every icon is white except Rainstorm, Fire, and Tsunami
Renamed it into what it should be named
Made the interior triangle dingies the same size, angles, etc (invisible at this size yet again)
