Make the telnet traffic a compact terminal view

Lines were as tall as a list item, with padding of more than the text. A
line is now as tall as its text, the view always follows the newest line
instead of pausing under the pointer, and a burst of lines is scrolled
once. The scrollback is a thousand lines.
