Fixed a future warning and error appearing on get_quote_table and get_live_price

[azwanzuharimi]

Fixed a future warning of the following functions:

1. get_live_price

• FutureWarning: Series.getitem treating keys as positions is deprecated. In a future version, integer keys will always be treated as labels (consistent with DataFrame behavior). To access a value by position, use ser.iloc[pos] return df.close[-1]

2. get_quote_table (Issue 110)

• FutureWarning: Passing literal html to 'read_html' is deprecated and will be removed in a future version. To read from a literal string, wrap it in a 'StringIO' object. tables = pd.read_html(requests.get(site, headers=headers).text)

• AttributeError: 'DataFrame' object has no attribute 'append'

Ran into the same thing today with get_live_price(). I can verify the commit fixes that issue.

get_quote_table() doesn't seem to be working anymore.
