simplify TS_All, so that it works on Ruby 1.9.3

test/TS_All.rb

 require 'fox16'
 require 'test/unit'
 
-class TS_All
-  def TS_All.suite

-      next if /^TC_/ !~ k

-      if constant.kind_of?(Class)
-#       puts "adding tests for #{constant.to_s}"
-	suite << constant.suite

 if __FILE__ == $0

   Dir.glob("TC_*.rb").each do |testcase|
