=item list

google's api way to get list of comments
return a list of loaded( no scraping is done here ) comments in list context,
a ref to the list otherwise.

=item parse_hybrid

when C<$Net::Google::Code::Issue::USE_HYBRID> is true,
we will try to load comments with the google's official api,
but as the api is not complete, we still need to do scraping to load
something( e.g. attachments ), this method is used to do this.
