Fixed HTML output, improved styling flexibility

[joshrickert]

Removed addslashes() calls that were creating malformed HTML, added additional spans for greater control of styling.

No problem. Pull request is submitted. I think it would knock out quite a few of your feature requests pertaining to styling flexibility (remove commas or spacer words, etc). It's been awhile so I can't quite remember, but I think it fixes your closing tag issue. I had the same debugging process and ended up realizing it was a problem with the HTML on the PHP side before it was ever handed off to your JS for display.
