Currently, the "Messages" panel shows a single speech bubble icon:
We should use a "double speech bubble" icon instead. This communicates better the conversation purpose and makes it easy to recognise (lower risk to become confused compared to a single geometric shape):
For performance reasons, Echo has copied these icons into the modules/icons/ folder, so those will need to be updated, the JSON files that make up the imagepack, and the code that adds the CSS classes.
I (@Legoktm) will mentor this task in GCI.
