Py2deb

-----------------------------

Use system wide pip-accel_ cache directories when running as ``root``.

.. _Release 0.5.3: https://github.com/paylogic/py2deb/compare/0.5.2...0.5.3
.. _pip-accel: https://github.com/paylogic/pip-accel

-----------------------------

Add dependency on ``chardet`` which is imported by ``python-debian`` but not
included in its installation requirements.

.. _Release 0.5.2: https://github.com/paylogic/py2deb/compare/0.5.1...0.5.2

-----------------------------

- Properly nest all Python modules under ``pydeb.*`` namespace.
- Renamed command line entry point from ``py2deb`` to ``pl-py2deb``.

Context: py2deb is developed at Paylogic_ where a lot of our internal command
line tools use the ``pl-*`` namespace inspired by the ``mk-*`` / ``pt-*``
namespace that `Percona Toolkit`_ uses.
