Add support for copying non-Unicode text to the clipboard. We also send a

simple 'styl' record along with it to specify the font and suchlike.  I'm
not sure it's worth making this optional in the way the RTF is in Windows.

    "-opt none" works around this.
  * When the last terminal window closes, the Edit menu doesn't get disabled
    immediately, which it should.
+ * When using the "VT100" font, text copied to the clipboard doesn't
+   get newlines in it, because that font has a graphic character at
+   position 0x0d.  Even if we did insert 0x0d manually, TextEdit
