Update putty to 0.60.
Patch provided by Jukka Salmi in PR 37056.

These features are new in beta 0.60 (released 2007-04-29):

 * Pressing Ctrl+Break now sends a serial break signal. (The previous behaviour
   can still be obtained with Ctrl+C.)
 * Serial ports higher than COM9 now no longer need a leading \\.\.
 * You can now store a host name in the Default Settings.
 * Bug fix: serial connections and local proxies should no longer crash all the
   time.
 * Bug fix: configuring the default connection type to serial should no longer
   cause the configuration dialog to be skipped on startup.
 * Bug fix: "Unable to read from standard input" should now not \ 
happen, or if it
   still does it should produce more detailed diagnostics.
 * Bug fix: fixed some malformed SSH-2 packet generation.
 * Other minor bug fixes.
