Scrapemark fails to decode hex-encoded HTML entities

[arshaw]

Scrape something that has an HTML entity encoded in hex (ex title of http://www.youtube.com/videos)

Entity should be decoded, instead a ValueError is thrown.

At the time of writing, the title for the above mentioned youtube page is (some whitespace removed for clarity):

<title>YouTube - &#x202a;Most viewed videos&#x202c;&lrm</title>

Testcode below:

#!/usr/bin/env python
import scrapemark

url = "http://www.youtube.com/videos"
data = scrapemark.scrape("<title>{{title}}</title>", url = url)
print data['title']

I've attached a patch
