irbtk.rb - irb with Ruby/Tk

If you want to use 'multi-tk.rb', give option '–multi-tk'. And if you want to use 'remote-tk.rb', give option '–remote-tk'. If you want both, you don't need to give both options, because 'remote-tk.rb' includes 'multi-tk.rb'. ( There is no trouble even if you give both options. )
