removing 'x' bits on source code and makefiles

add some basic test cases to the unittests (needs expanded)

add file info to setup.py

add Makefiles to minion/modules/netapp/* and minion/modules/iptables/*
to make make clean work

try to hit up more of the subdirs, etc, when running "make clean"

Previously we had overlord, minion, modules, and func all at the root of
the source tree. After install these would all be shuffled below func.
Relocated them in the source tree to reflect this.
