Configure the Peach Exporter for the new deployment model.

Add a well formatted setup.py file.
Remove small alerts in PeachExporterPlugin.py.
The precommit hook detects dynamically if PEP8 is installed.

If so, it is ok.
If not, it displays a nice message warning the user and prevents the commit to be done.
Move Peach files in the accurate directory

Finish the installation package of the Peach Exporter Plugin.
Update the call of the function getTypeVariable()

Which is now called getVariableType().
ReferencedVariable integration has been temporarily removed.
Add httplib2 dependency in the main setup.py.
Add the graphviz dependency in the README.rst
Modify the pre-commit hook so it won't check the header in .rst files.

This header is not in the README file and that generated an error.
Add also some missing comas.
