Anchor tag, href attribute needs entity & convert to & for proper URL

[johnathan10102]

When a comment/post is passed through the HTML/XHTML filter, kses.php, the URL of an anchor tag, href attribute needs the HTML entity for the ampersand needs to be converted to character form.

Example, A user posts a comment to a blog post.

Input : Hey check my gallery too! <a href="​http://hissite.com/index.php?page=art&work=23">Gallery!</a>
Output : Hey check my gallery too! <a href="​http://hissite.com/index.php?page=art&amp;work=23">Gallery!</a>

Now the url to his gallery is broken :/. Its no longer $_GETwork rather $_GETamp;work.

I have created a patch for this though.
