Pyliblo

* New and improved documentation, built from docstrings using Sphinx.
* Add Server.add_bundle_handlers(), thanks to David Honour and Paul Weaver.
* Fix sending 64-bit values with Python 3 and on some 64-bit systems,
thanks to Sebastian Ramacher.
* Cython is now a mandatory build dependency. The generated liblo.c has
been removed from the release tarball.
* The minimum version of liblo required by pyliblo is now 0.27.

* Add function Server.del_method(), thanks to a patch from Артём Попов.
* Use Python 3 compatible syntax in the send_osc and dump_osc scripts.
This also means that 2.6 is now the minimum supported Python version.
* Use setuptools if available, thanks to Chris Arndt.

* Changed send functions to raise an IOError if sending failed (probably
most useful with TCP connections).
* Lots of code cleanup and deobfuscation.
* Included unit tests in release tarball.

* Support Python 3.x. As a result, pyliblo can no longer be built with
Pyrex, and requires Cython >= 0.12 instead.
* Added free() method to Server and ServerThread classes.
* Added fileno() method to Server and ServerThread classes (thanks to
Edward George).
* Prefer read-only properties over getter methods (which still exist, but
are now deprecated).
* Added proper docstrings (copied from the HTML docs).
* The minimum version of liblo required by pyliblo is now 0.26.

* Release the Python GIL inside Server.recv().
* Fixed a possible segfault when the error handler was called from the
* liblo server thread.

* Changed license from GPL 2 to LGPL 2.1 (as did liblo in version 0.26).
* Added protocol parameter to the Server class. Among other things, this
allows TCP connections.
* The minumum version of liblo required by pyliblo is now 0.24.
* pyliblo can now be built with either Pyrex or Cython.
