    chatView: Add shortcuts to jump to top/bottom
    
    GtkTextView's built-in bindings, <ctrl>Home and <ctrl>End, don't work,
    as they are used by the first-room/last-room application shortcuts. As
    we hide the cursor and don't have horizontal scrolling in the chat log,
    the built-in bindings for jumping to the beginning/end of the current
    line aren't useful, so use them to move to the top/bottom of the
    chatlog instead.
