smiley escaping fixes
Smileys need to be double-escaped to work, since the smiley plugin runs as a sanitize hook, and markdown helpfully removes one level of escapes first. There were some bugs in the smiley handling code that made escaped smileys still be expanded. After unescaping a smiley, it needed to move pos forward past it or the next pass would expand it. Also, once the m//g got to the end, it seemed to loop back through and make one more pass (a difference in perl 5.10's regexp exngine? I observed that pos was undefined when this happened, so added a `last unless defined pos`.
