Monochrome Icon for "no unread mails"

[riidom]

I like to have a monochrome icon for when there are no unread mails, and the default TB icon with number on top for notification. Since there was no good icon, I made one myself, for anyone who likes it, I attached it. It is 64x64px, but probably be displayed way smaller (for example, mine is ~40% size when it sits in my tray).

Since it is based on the original TB icon (ofc), but simplified for the small size, I'm not sure if I can pick a license myself, but if so, it goes by CC-0.

(github doesn't let me upload the .svg unzipped): birdtray_nomail.zip

Edit:

further simplified, and if this can go into the project, I'd be happy about that, just not sure how to integrate and make a PR for this, so I hope this way is good enough until someone proficent takes care.

Thanks for this. The normal colour icon looks a bit out of place in dark mode as all the other tray icons are white.
