Allows quoting of messages when replying. Based on the plugin by Michael Nolan (http://bbpress.org/plugins/topic/quote/).
- Using JS if the user is viewing the last page of a topic. In this way, a user can quote more than one message in a reply, because the quoted post is retrieved using AJAX.
- Using the mechanism of the original plugin.
Among added features: the suggested ones in the comments of the original plugin, plus nonces, removal of nested blockquotes and localization.
