Cache the tinted SVGs for MFileBody as data URLs (#559)

Browse source 
* Use a list of callbacks for things that need tinting.

Rather than gutwrenching the internals of TintableSVG inside the Tinter.

* Share a data: url for the tinted download svg in MFileBody

* Check image exists before tinting

* Add comments

* Use fetch+DomParser rather than XMLHttpRequest

* Remove comment about XMLHttpRequest
