Adding comment formatting option to the nopaste plugin

This patch adds the ability to configure the format of the session as
is sent to the nopaste server. Formerly, the perl commands were
commented out and the output of them was not. This patch provides a
configuration option to swtich that behavior so that by default the
perl code is not commented out, but the output from each statement is
and this can be optionally switched back to the former behavior.

+
+The format sent to the nopaste server can be adjusted with the
+C<nopaste_format> option. By default, the output of each perl
+statement is commented out, and the perl statements themselves are
+not. This can be reversed by setting the C<nopaste_format> attribute
+to C<comment_code> like this in your re.pl file:
+
+C<< $_REPL->nopaste_format( 'comment_code' ); >>
+
+The default of commenting out the output would be set like this:
+
+C<< $_REPL->nopaste_format( 'comment_output' ); >>
+
+These options can be set during a Devel::REPL session, but only affect
+the future parts of the session, not the past parts.
