handle interactive xkcd comics (#6474)

* handle interactive xkcd comics

Some xkcd comics tend to be interactive and can only be played in a regular browser
These cannot be loaded in the app and the reader loads indefinitely
Instead, we throw a text image with a message to open in browser

the div#comic img attribute will be null/empty in case of parsing interactive
comics and is then replaced with an image warning

uses fakeimagepl to generate image from text
