Fix for 'Module build failed: TypeError: Object.keys called on non-object'#82

The object-assign package returns the 'native' Object.assign' when it exists.
When using traceur@0.0.58 it creates an Object.assign implementation using Object.keys which fails with non-object values.
A workaround was to add `require('babel-loader');` before `var traceur = require('gulp-traceur');` in my gulpfile.
