Fix to obey --build-dir when copying files
Based off the original build.json and committed output files, it appears 3-copy.js build files were intended for assets, not assets-global. Specifying `global-config: false` will make this happen.
Update to test #9's build.json to reflect the change in target paths for copy commands from commit 484f02
Merge pull request #79 from derek/buildcopy-fix
