This replaces the self-built components for the user list with StatusQ's
list item component and also addresses some of the quirks that existed in the UI
related to that original component.
The user list is now responsive and properly aligned.
**This depends on StatusQ v0.18.0**
Moved Message component & dependencies to shared
for usage import shared.views.chat 1.0 and accordingly
import shared.controls/panels.chat 1.0
Closes#3927
Probably slipped through in the refactor: `getLinkStyle` was defined
in to places, was probably meant to live only in `Utils`.
In addition, it expected a `wrapper` expression which wasn't defined.
This commit fixes it by removing the second declaration of that function
and passing a third parameter to the one defined in `Utils`.
