The problem in textrite::rite came from the use of look-behind assertions in Perl regexp. I've changed all of them so that look-behind is not needed anymore. The same problem occurs in interpolate_fancy::__ANON__, but I'm not going to look into it yet.

The other problem was that textrite::rite was called for all the stories, including the ones that were not displayed (which was most of them). I changed the internal structure of the main script so that the processing of the story happens after discarding the non-displayed ones.
