<sub> tag in RSS feed breaks some readers #12

The <su\b>th tags break some RSS feed readers causing them to display "null" as the title.

While inconvenient, the RSS title element, by DTD rules, contains PCDATA, rather than CDATA, so those <sub> should not cause any problems. If the RSS reader you use breaks on them, then it'll be worth filing a bug with whoever maintains it and have them fix this issue. I'll think about whether there's a simple fix that doesn't involve "blank out HTML tags entire", but in the mean time this is mostly an RSS interpreter bug.
