We now analyze ChatLines (lazily) for interesting stuff like URLs and channel names,
and when hovering on them, underline them (and later also change the mouse cursor, I guess).
Still missing: action on click, also we still have some visual glitches while selecting.
Also I think we'll provide a context menu on right click later.
