[CM] Snd 11.13

[Bill Schottstaedt]

Snd 11.13

s7: make-hash-table-iterator.

    map and for-each accept any applicable object as the first argument.

    format's ~{...~} directive can handle any applicable object.

    the thread stuff has been exported to s7.h.

    s7_set_begin_hook (see s7.html#s7inathread and s7.html#replrescue)
      The basic problem is that the GUI toolkits are not thread-safe, but we
      want the GUI to remain responsive even if s7 is caught in an infinite
      loop in the listener.  This also gives a way to break out of any long
      computation without relying on Unix signals and weird keystrokes.
      This is tied to C-g in the listener, so ws-interrupt (ws.scm) is
      now a deprecated no-op.

lots more forth and ruby stuff thanks to Mike Scholz.

checked: gtk 2.99.0|1|2|3, gtk 3.0.0, FC14 (gcc 4.5.1)

Thanks!: Rick Taube, Hartmut Noack, Mike Scholz.
