Added an unmodified copy of SCons to third_party.

scons-2.0.1/engine/SCons/Tool/javac.py

+"""SCons.Tool.javac
+
+Tool-specific initialization for javac.
+
+There normally shouldn't be any need to import this module directly.
+It will usually be imported through the generic SCons.Tool.Tool()
+selection method.
