Updates the Win32 VM to 3.4. No major changes since 3.2.3 but merely a few
fixes in various areas.

* The VM now prints the list of loaded plugins if it crashes (this is helpful for finding out if the crash is due to some outdated external plugin
  for example).

* A typo for handling the direct sound preference prevented remembering the
  pref correctly.

* A workaround for the case that the default printer is a network printer and inaccessible upon startup. This could lead to _very_ long pauses
  when starting Squeak.

* A fix for the initial window size as suggested by Eddie Cottongim was added.

* The GNU make file has been updated to use cp/rm from the 1.2 tool chain.
