* lib/xmlrpc/client.rb: use "" instead of "." if prefix argument is

nil in proxy methods. nil is default value.

* test/xmlrpc/test_webrick_server.rb, test/xmlrpc/webrick_testing.rb:
  use threads instead of forking. this should fix issue #1208
  (http://rubyforge.org/tracker/?func=detail&atid=1698&aid=1208&group_id=426).
  removed testing of SSL enabled servlet as this hangs.
