setup.py - pep8 cleanup
setup.py - python paths for apache fixes

Previously there was a patch put into setup.py that would
fix the python path in apache/adagios.conf.

The previous patch made assumptions on how the build structure would
look like and setup.py was not working on debian machines.

I fixed the path replacement logic but i still feel like this should be done
at packaging time.
adagios.conf - Clarifications to default values

Some default values where missing from the configuration files.

* pnp_filepath
* destination_directory
Debian package directory created

So far very experimental
