Issue:
Python message extractor doesn't respect unicode_literals in __future__
`extract_python` of Babel doesn't respect `from __future__ import unicode_literals` in Python 2.x.  With the below example code:

```python
# coding: utf-8
from __future__ import unicode_literals
_('\xa0')
```

We get this encoding error:

```
UnicodeDecodeError: 'utf8' codec can't decode byte 0xa0 in position 10: invalid start byte
```

A workround is to use `u''` literals explicitly:

```python
# coding: utf-8
from __future__ import unicode_literals
_(u'\xa0')
```

Pull request description:
Python message extractor respects unicode_literals in __future__
This patch fixes #426.

   +----------+-----------------------------------------------------------------+
 
 
-Rounding Modes
-==============
-
-Since Babel makes full use of Python's `Decimal`_ type to perform number
-rounding before formatting, users have the chance to control the rounding mode
-and other configurable parameters through the active `Context`_ instance.
-
-By default, Python rounding mode is ``ROUND_HALF_EVEN`` which complies with
-`UTS #35 section 3.3`_.  Yet, the caller has the opportunity to tweak the
-current context before formatting a number or currency:
-
-.. code-block:: pycon
-
-    >>> from babel.numbers import decimal, format_decimal
-    >>> with decimal.localcontext(decimal.Context(rounding=decimal.ROUND_DOWN)):
-    >>>    txt = format_decimal(123.99, format='#', locale='en_US')
-    >>> txt
-    u'123'
-
-It is also possible to use ``decimal.setcontext`` or directly modifying the
-instance returned by ``decimal.getcontext``.  However, using a context manager
-is always more convenient due to the automatic restoration and the ability to
-nest them.
-
-Whatever mechanism is chosen, always make use of the ``decimal`` module imported
-from ``babel.numbers``.  For efficiency reasons, Babel uses the fastest decimal
-implementation available, such as `cdecimal`_.  These various implementation
-offer an identical API, but their types and instances do **not** interoperate
-with each other.
-
-For example, the previous example can be slightly modified to generate
-unexpected results on Python 2.7, with the `cdecimal`_ module installed:
-
-.. code-block:: pycon
-
-    >>> from decimal import localcontext, Context, ROUND_DOWN
-    >>> from babel.numbers import format_decimal
-    >>> with localcontext(Context(rounding=ROUND_DOWN)):
-    >>>    txt = format_decimal(123.99, format='#', locale='en_US')
-    >>> txt
-    u'124'
-
-Changing other parameters such as the precision may also alter the results of
-the number formatting functions.  Remember to test your code to make sure it
-behaves as desired.
