Add a way to download only the full headers and not the rest of the content

See original GitHub issue

Expectead behavior

Print complete header when pressing Show headers. I don’t care about highlighting, plaintext is okay but print the complete header.

Actual behavior

k9 is not showing the full header. It appears as if just some special/known(?) parts of the header are chosen.

Example

This is a classical spam-header – hence I leave the senders information.

Thank you for your answer! But anyway, the HTML-content (in this case images) is being displayed in it’s full glory as soon as I click on “Download complete message”.

So, in this case, to read the full header, I have to click “Download complete message” and WebView then renders everything, right? Hum. 😦

K-9 does not execute HTML content.

It passes the raw string data to Android WebView. WebView renders the HTML but does not fetch remote content, unless told to (it’s network connection is disabled). We don’t tell it to fetch remote content (by enabling it’s network connection) until you click that button, regardless of whether we have the full message or not.

We also remove all scripts using a HTML cleaner tool.
