[feature] Force text/html display by default - per user config

[fpeterschmitt]

Hi,

I think the title is well describing my request: adding a configuration (and then some code...) option to force type view of mails: raw text or html.

And of course, with a cleanup of all html tags before displaying the text.

This should increase privacy and security for everyone caring about that. Any JS code or tracking picture will be inoperative.

Also, a fast switch in the view would be interesting.

Furthermore, we could imagine the possibility to add per-domain/address rules to display in HTML or raw text some mails.

I agree. 👍 HTML email is pretty much for old ladies.
