Title: Render missing images within rich text as broken images, rather than throwing IOError during rendering

Fixes #801 - also addresses the issue encountered in https://groups.google.com/d/msg/wagtail/z4q6JEMRzko/JApY0jX3rqsJ where unrelated IOErrors while creating image renditions (e.g. missing image libraries) were being masked by the try/catch.
