Prospector

---------------
* `116 <https://github.com/PyCQA/prospector/issues/116/>`_ Comparison failed between messages with numeric values for character and those with a `None` value (thanks smspillaz)
* `118 <https://github.com/PyCQA/prospector/issues/118/>`_ Unified output of formatters to have correct output of str rather than bytes (thanks prophile)
* `115 <https://github.com/PyCQA/prospector/issues/115/>`_ Removed argparse as an explicit dependency as only Python 2.7+ is supported now

---------------
* `112 <https://github.com/PyCQA/prospector/issues/112/>`_ Profiles will now also be autoloaded from directories named `.prospector`.
* `32 <https://github.com/PyCQA/prospector/issues/32/>`_ and `#108 <https://github.com/PyCQA/prospector/pull/108/>`_ Added a new 'xunit' output formatter for tools and services which integrate with this format (thanks to [lfrodrigues](https://github.com/lfrodrigues))
* Added a new built-in profile called 'flake8' for people who want to mimic the behaviour of 'flake8' using prospector.

---------------
* The profile validator would load any file whose name was a subset of '.prospector.yaml' due to using the incorrect comparison operator.
* Fixing a crash when using an empty `ignore-patterns` list in a profile.
* Fixing a crash when a profile is not valid YAML at all.
* `105 <https://github.com/PyCQA/prospector/pull/105/>`_ pyflakes was not correctly ignoring errors.

---------------
* pep8.py 1.6.0 added new messages, which are now in prospector's built-in profiles

---------------
* Fixing a crash when using pep8 1.6.0 due to the pep8 tool renaming something that Prospector uses

---------------
* `104 <https://github.com/PyCQA/prospector/issues/104/>`_ The previous attempt at normalising bytestrings and unicode in Python 2 was clumsily done and a bit broken. It is hopefully now using the correct voodoo incantations to get characters from one place to another.
* The blender combinations were not updated to use the new PyFlakes error codes; this is now fixed.
