Prospector

---------------
* Demoted frosted to be an optional tool - this is because development seems to have slowed and pyflakes has picked up again, and frosted how has several issues which are solved by pyflakes and is no longer a useful addition.
* `78 <https://github.com/PyCQA/prospector/issues/78/>`_ Prospector can now take multiple files as a path argument, thus providing errors for several files at a time. This helps when integrating with IDEs, for example.
* Upgrading to newer versions of Pylint and related dependencies resolves `73 <https://github.com/PyCQA/prospector/issues/73/>`_, `#75 <https://github.com/PyCQA/prospector/issues/75/>`_, `#76 <https://github.com/PyCQA/prospector/issues/76/>`_ and `#79 <https://github.com/PyCQA/prospector/issues/79/>`_
* `74 <https://github.com/PyCQA/prospector/issues/74/>`_, `#10 <https://github.com/PyCQA/prospector/issues/10/>`_ Tools will now use any configuration specific to them by default. That is to say, if a `.pylintrc` file exists, then that will be used in preference to prospector's own opinions of how to use pylint.
* Added centralised configuration management, with an abstraction away from how prospector and each tool is actually configured.
* Removed the "adaptors" concept. This was a sort of visitor pattern in which each tool's configuration could be updated by an adaptor, which 'visited' the tool to tweak settings based on what the adaptor represented. In practise this was not useful and a confusing way to tweak behaviour - tools now configure themselves based on configuration options directly.
* Changed the default output format to be 'grouped' rather than 'text'
* Support for Python 2.6 has been dropped, following Pylint's lead.
* Using pylint 1.4's 'unsafe' mode, which allows it to load any C extensions (this was the behaviour for 1.3 and below). Not loading them causes many many inference errors.
* `65 <https://github.com/PyCQA/prospector/issues/65/>`_ Resolve UnicodeDecodeErrors thrown while attempting to auto-discover modules of interest by discovering target python source file encoding (PEP263), and issuing only a warning if it fails (thanks to [Jeff Quast](https://github.com/jquast)).

---------------
* Pylint dependency version restricted to 1.3, as 1.4 drops support for Python 2.6. Prospector will drop support for Python 2.6 in a 0.8 release.
* File names ending in 'tests.py' will now be ignored if prospector is set to ignore tests (previously, the regular expression only ignored files ending in 'test.py')
* `70 <https://github.com/PyCQA/prospector/issues/70/>`_ Profiles starting with a `.yml` extension can now be autoloaded
* `62 <https://github.com/PyCQA/prospector/issues/62/>`_ For human readable output, the summary of messages will now be printed at the end rather than at the start, so the summary will be what users see when running prospector (without piping into `less` etc)

---------------
* The E265 error from PEP8 - "Block comment should start with ' '" - has been disabled for anything except veryhigh strictness.

---------------
* `60 <https://github.com/PyCQA/prospector/issues/60/>`_ Prospector did not work with Python2.6 due to timedelta.total_seconds() not being available.
* Restored the behaviour where std_out/std_err from pylint is suppressed

---------------
* `48 <https://github.com/PyCQA/prospector/issues/48/>`_ If a folder is detected to be a virtualenvironment, then prospector will not check the files inside.
* `31 <https://github.com/PyCQA/prospector/issues/31/>`_ Prospector can now check single files if passed a module as the path argument.
* `50 <https://github.com/PyCQA/prospector/issues/50/>`_ Prospector now uses an exit code of 1 to indicate that messages were found, to make it easier for bash scripts and so on to fail if any messages are found. A new flag, `-0` or `--zero-exit`, turns off this behaviour so that a non-zero exit code indicates that prospector failed to run.
* Profiles got an update to make them easier to understand and use. They are mostly the same as before, but `the documentation <http://prospector.readthedocs.org/en/latest/profiles.html>`_ and command line arguments have improved so that they can be reliably used.
* If a directive inline in code disables a pylint message, equivalent messages from other tools will now also be disabled.
* Added optional tools - additional tools which are not enabled by default but can be activated if the user chooses to.
* Added pyroma, a tool for validating packaging metadata, as an optional tool.
* `29 <https://github.com/PyCQA/prospector/issues/29/>`_ Added support for pep257, a docstring format checker
* `45 <https://github.com/PyCQA/prospector/issues/45/>`_ Added vulture, a tool for finding dead code, as an optional tool.
* `24 <https://github.com/PyCQA/prospector/issues/24/>`_ Added Sphinx documentation, which is now also `available on ReadTheDocs <http://prospector.readthedocs.org/>`_

---------------
* Fixed pylint system path munging again again
