Description

Using future 0.15.2 in Python 2.7:

>>> from html import unescape
*** ImportError: cannot import name unescape

Using plain Python 3.4 it works. The function was introduced in Python 3.4, see documentation.

Please add it.

Research direction
Investigate the python future library structure, specifically the `future/standard library/` directory where Python 3 stdlib functions are backported. Look at how similar functions like `html.escape` or other html module functions are implemented. The issue requires adding `html.unescape` to match Python 3.4+'s behavior. Check if there is an existing `html` module in the backport and add the missing function using `from html.parser import HTMLParser` or similar approach. Verify with tests.
