v0.9.4-pre

• Newlines survive in string simulation inputs. A value like line1\nline2 appeared in the
  input field with the newline missing, and because leaving the field committed whatever it held,
  clicking into a string input and clicking away was enough to send the shortened value back to
  the model -- with nothing typed and nothing to see. \r\n lost both characters. A single-line
  field cannot hold a newline at all, so strings are now shown and typed escaped, using the same
  escapes as the chr number format: \n, \r, \t, \0, \xNN and \\. Table cells show
  them too, instead of collapsing a newline into a space, and a newline can now be entered in the
  first place. An input nobody typed in is never written back.
