Extracting natives from the classpath into the working directory is a risky hack. In the long term, JME should probably use a native-library loader analogous with that of LWJGL v3.

JME first looks working directory if it is writable then chooses that else it looks for user cache directory inside user.home directory, if found, will extract there, if not found then it will extract to userHome/.jme3.

We should omit the check for "working directory" step above.
