Vuze/Bigly is based on NDT 3.6.2b, so their changes are manually merged here. This rev does not compile, requires swingemu package to follow. Changes: - Add external start hook to Tcpbw100 from BiglyBT - Replace all Swing/AWT classes with emulations from BiglyBT (included in next checkin) - Leave classes in edu.internet2.ndt package rather than moving to com.vuze.plugins.mlab heirarchy as Vuze/BiglyBT did - Change IPv6 support setting to use I2P class for detection - Change in-progress field to an AtomicBoolean - Change from System to I2P logging - Change JSON library package - Comment out some applet code - Javadoc fixes
