in features/desktop/aspect_navigation.feature:18 we quickly leave the page
before waiting for the request to finish. By making the HTTP call
synchronous we wait for it to finish before we reflect the change in the DOM,
thus giving Capybara a chance to wait for it. Also let Capybara wait longer.
This should random failures of the aforementioned cuke rarer.

- updates underscore to 1.5.2 and backbone to 1.1.0

backbone had some breaking changes:
- fix url/urlRoot handling in models & collections
- options are no longer attached to the view by default
- collections reset when 'fetch' is called, tell it to keep the existing
  models

other changes:
- fix some events triggering multiple times in connection with deleting
  a model
- use document fragments instead of an element array for stream entries
- adapt jasmine and cucumber specs to the changed code
  * no longer test the backbone router as part of our code
  * jasmine factory already returns model instances, no need to wrap
    that again
