Add entity2unicode in `django.utils.html`

[rafael+django@…]

The html utils of Django could have this function:

import htmlentitydefs
entity_re = re.compile('&([a-z]+);', re.I)
def entity2unicode(text):
    for entity in entity_re.findall(text):
        print entity
        text = text.replace('&%s;'%entity, htmlentitydefs.entitydefs[entity].decode('iso-8859-1'))
    return text

Maybe it could be useful for someone else

Things in django.utils are mostly support functions for Django itself, not functions designed for external use.
