Bug 974867 - [MMS]Auto suggestion for email address r=Julien

https://bugzilla.mozilla.org/show_bug.cgi?id=974867
this line is too long, please break it in 2 lines:
```javascript
/*global MockContact, Contacts, fb, MockFbReaderUtilsObj,
         MockSettings, MocksHelper */
```

(be careful: nothing than white space between the comma on the previous line and "MockSettings")
