By using a magic comment such as

```javascript
   // erp5_monaco_editor_include: ../other.js other
```
we can tell monaco editor that other.js will be loaded before the
current javascript file, which helps the typescript compiler in
diagnosing errors and providing completions.

rsvp, renderjs and jio are still always loaded because they are used in
almost all our javscripts.
