Update addon.xml

Hello it's me again :)
I posted about dependancy missing BeautifulSoup.
You added BS version 4 wich is not compatibile with this addon.
Of course I changed the service.py from:

from BeautifulSoup import BeautifulSoup

to:

from bs4 import BeautifulSoup 

As i saw in some XBMC forum topic. To make it use bs4.
But it crash with ERROR: list out of bound in log.

With BS v3 there's no problem and work 100% ok.
