RSS Feed Validation Issues

[MobileCS]

When using the W3C Feed validator (https://validator.w3.org/feed/), it complaining about a few things when validating the forum RSS feed.

title should not contain HTML: "

category should not contain HTML: &

Missing atom:link with rel="self"

-------

So it appears the RSS page is missing the line:

<atom:link href="http://www.example.com" rel="self" type="application/rss+xml" />

Also, using "html_entity_decode" on title and category tag content should solve the other issues.
