faq.rst: Mention DATE and TIME unserialized to str

[msabramo]

pymssql does not unserialize DATE and TIME columns to
datetime.date and datetime.time instances

[rsyring]

The code example uses 'select * from foo':

cursor.execute("SELECT * FROM foo")
cursor.fetchall()
[{u'date': u'2014-01-09', u'time': u'06:17:00.0000000',
u'datetime': datetime.datetime(2014, 1, 9, 9, 17, 56, 623000)}]

Was that intentional?

Well, that was the name that I used locally, but that's kind of silly and I thought I should show what the table looks like so people can reproduce it if they want (or we can run automated tests at some point in the future).

So I enhanced it in #167.
