code fix in Display.js.  Moved .txt files to /test folder (they're only needed when testing).  Created binaries based on node-webkit v0.7.5 ia32 and x64 binaries.  These should work with Debian Wheezy.  These binaries do not work on distros based on Ubuntu 14.04 (unless, for some reason, libudev has been downgraded to .so.0 from .so.1)
