 refreshes and combines the previous patches. @mattheu your original test
 function had `ismap` as an allowed property on `<img />` tags. I couldn't
 that in the history of `kses`. After removing that your tests pass
 properly.

 I also added a test to ensure a bad protocol is properly stripped out of
 the `srcset` attribute.
