* lib/soap/generator.rb: better XML pretty printing.

* lib/soap/encodingstyle/soapHandler.rb: remove unnecessary namespace
  assignment in the element which has "encodingStyle" attribute, and add
  necessary namespace assignment for "arrayType" attribute.

* test/soap/calc/test_calc_cgi.rb: take over $DEBUG to ruby process through CGI.
