[NLRS] RainScatter update for Java 7

[aflowers at frontiernet.net]

It's hot here, so I'm staying in my cool basement putting together patch this afternoon so that the storm tables will load on Java 7 VMs.  I need some guinea pigs to try it out.  If you are interested, send me a email direct.  It will come as a zip file that you can extract in another folder, so you don't have to overwrite/upgrade anything that already exists.

Happy 4th,
