Code smell: Avoid needless decorations

* Replaced 704 occurances of (.*)\b([a-z_]+)\(\) with \1\2

  3 Examples:

      The code:
          ctx = OpenSSL::SSL::SSLContext.new()
      becomes:
          ctx = OpenSSL::SSL::SSLContext.new
      The code:
          skip()
      becomes:
          skip
      The code:
          path = tempfile()
      becomes:
          path = tempfile

* Replaced 31 occurances of ^( *)end *#.* with \1end

  3 Examples:

      The code:

      becomes:

      The code:
          end # Dir.foreach
      becomes:
          end
      The code:
          end # def
      becomes:
          end
