Note: karma with dart is still not working
because of how `karma-dart` loads `package:…` dependencies.
Usage:
```
karma start karma-js.conf.js
karma start karma-dart.conf.js
```
Make sure to set `DARTIUM_BIN` env variable.
Refactors `js2dart`:
- live outside of the traceur module (`tools/js2dart/index.js`)
so it can be reused by gulp and karma
- automatically build the sources in memory,
so that `js2dart` can be used without running `gulp build` first
- provide a way to specify the moduleName of a compilation run
independently of the input filename. This helps error messages
and source maps (not yet enabled) to report the correct file name
Changes project setup:
- add module `test_lib` that contains the primitives for tests
(e.g. `describe`, `it`, …)
- clean up some sources that had errors in them
- module names in transpiled js and dart files don’t contain
`lib`, `test` nor `src` any more (e.g. `di/di`).
