Update to 2.0:

2.0 (2015-05-18)
++++++++++++++++

- Added support for Unicode IDNA Compatibility Processing (aka Unicode
  Technical Standard #46). Big thanks to Jon Ribbens who contributed this
  functionality.

Log message:
Import py34-idna-1.1 as www/py-idna.

A library to support the Internationalised Domain Names in Applications
(IDNA) protocol as specified in RFC 5891. This version of the
protocol is often referred to as IDNA2008 and can produce different
results from the earlier standard from 2003.

The library is also intended to act as a suitable drop-in replacement
for the encodings.idna module that comes with the Python standard
library but currently only supports the older 2003 specification.
