page_msg concept are broken... Must be lazy...

[JensDiemer]

I found a very bad thing about the self.page_msg: After the template engine has render the message template tag into the page, there can't be added new messages :( That's logical, isn't it?

I found the bug, because i used self.page_msg() in the back_links() plugin and i can't see the messages in the page...

Solution: The page_msg must be lazy rendered. It must be went into a middleware.
