$ node build modules=ALL requirejs - dist/all* is clean of changes - fixed bug in build.sh that would prevent dist/all.require.js from compiling properly - Updated test.js to include test_script.js fixtures - NOTE: Qunit tests largely incompatible with requirejs version... need more insight on how Qunit works to get fabric in the namespace since it is no longer a global when built as an AMD module.
