Update to the latest 1.0.1 SCons checkpoint.
The build engine (library) is getting added in a scons-local subdirectory, without version number, so we can track future changes, and more easily merge any local mods we've had to make in a pinch. Removing the old scons-local-0.98.3 directory will come seprately to avoid Rietveld limitations.
