Oembed fails on Soundcloud

[markfinger]

Given a url https://soundcloud.com/vvv/faded-inscription-feat-bvitae, the following error is raised: ValueError: invalid literal for int() with base 10: '100%'.

The underlying issue seems to be that soundcloud's oembed implementation[0] differs from the spec[1], and they return a string which cannot be coerced to an int.

They return 100% for the width field, unfortunately the respective field on the fluent-contents model is an IntegerField and the coercing fails.
