Mumla now let's you post images in the chat. Thank you Bartkk0 for implementing this, and also fixing an issue with own chat messages disappearing!

Also some messages have been reworked and translated. Thanks to Allan, Bartkk0, J. Lavoie, Matthaiks, Omar, Oğuz Ersen, deluxghost, nautilusx, pjammo.

Translating is done here: https://hosted.weblate.org/projects/mumla/
