Test (#20)

* change apache_data to apache_user in all

* no libapach2 in centos. just php. no php-magick in centos

* remove redundant vars entries

* do not create apache user

* missed one pound sign

* soft code all references to apache_user

* centos requires older setuptools

* revert ansible_lsb.id in xsce.yml

* try getting recent pip

* move pip download to 2prep so that kalite success is not dependent on iiab coming first

* still need to replace setuptools in kalite

* add curl -- needed in debian

* massivly substitue iiab for xsce, and rename files

* completed runansible

* centos fixes,install  pip

* appliance means no iptables rules

* change to earlier version of setuptools for centos

* delete file duplicate, hopefully unnecessary. generate the offline docs

* wiki docs errors

* create the admin group -- deleted earlier

* use the --yes option with pip uninstall

* base of repo moved from schoolserver to iiab, unleashkids.org->iiab.io

* network detection broken due to tupo
