Thunderbird: Allow users to change naming convention of "save mail as" (ctrl + s) via config

[maxgrrs]

Currently when I press Ctrl + s while a mail is open the proposed name for the .eml file that will be saved as something like '[subject] - [sender] - [date]' which is not what suits my needs.

Same thing is discussed here and in other forums.
The workaround with this import/export add on tool is not really nice as it does not apply to the ctrl + s function.

Would be great if a config line gets implemented where the naming convention can be changed to own needs.

There maybe already is the same idea here, but I was not 100% sure so I wrote this anyway.

Implementation would be nice 🙂
