[Rxtx] RXTX rebundled (fwd)

[Gregg Wonderly]

Automatic loading of the native libraries is a big win for portability of applications between OSes.  That certainly should be in place.  Support for Maven is a separate issue, but one which I think makes sense in this day and age.

BUT: The artifact does not contain the native libraries and there was no suggestion on how to handle this issue "the maven way". I also found the setup-explanation in the wiki a bit away from "state of the art" (changing the JRE installation isn't practivle for stand-alone desktop applications etc...). So I rebundled your rxtx library and extened it a little bit:

This loader detects the OS + ARCH and extracts the correct native lib from JAR to the temp folder of the OS. Finally the extracted native lib is loaded from temp folder. If JVM terminates, the temp native lib files are removed.
