dnspython 1.15.0 released

[Bob Halley]

dnspython 1.15.0 is now available on pypi and at www.dnspython.org.  My thanks to the people who have contributed to this release!

### New since 1.14.0:

* IDNA 2008 support is now available if the "idna" module has been

  installed and IDNA 2008 is requested.  The default IDNA behavior is

  still IDNA 2003.  The new IDNA codec mechanism is currently only

  useful for direct calls to dns.name.from_text() or

  dns.name.from_unicode(), but in future releases it will be deployed

  throughout dnspython, e.g. so that you can read a masterfile with an

  IDNA 2008 codec in force.

* By default, dns.name.to_unicode() is not strict about which

  version of IDNA the input complies with.  Strictness can be

  requested by using one of the strict IDNA codecs.

* The AVC RR is now supported.

### Bugs fixed since 1.14.0:

* Some problems with newlines in various output modes have been

  addressed.

* dns.name.to_text() now returns text and not bytes on Python 3.x

* Miscellaneous fixes for the Python 2/3 codeline merge.

* Many "lint" fixes after the addition of pylint support.

* The random number generator reseeds after a fork().
