Format the items in `lst` as a list.
>>> format_list(['apples', 'oranges', 'pears'], locale='en')
u'apples, oranges, and pears'
>>> format_list(['apples', 'oranges', 'pears'], locale='zh')
u'apples、oranges和pears'
>>> format_list(['omena', 'peruna', 'aplari'], style='or', locale='fi')
u'omena, peruna tai aplari'
These styles are defined, but not all are necessarily available in all locales.
