requirejs support added via "requirejs" build.sh option
$ 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.
