fixed problem where module.exports, which is needed by node.js gets incorrectly minified by Closure. Simple change from module.exports = Module to module['exports'] = Module fixes this. Added simple test case compiling with --O2 -closure 1 to /tests/Module-exports
Added test_module_exports_with_closure to tests/test_other.py, run with ./runner.py other.test_module_exports_with_closure
replaced tests/Module-exports in path_from_root with 'tests', 'Module-exports' to be more friendly multiple OSs
change test_module_exports_with_closure to only execute the run_js test when engine == NODE_JS, this test is really checking that the module.exports stuff works in node
removed comment in src/shell.js and explicitly called run_js with engine=NODE_JS as requested
Merge branch 'fix-module-exports-with-closure-try2' of github.com:fadams/emscripten into incoming
