The 'manual fixups' are:
- incorrect use of dict.items() where dict.iteritems() was meant; this
results in list(dict.items()), which I changed to dict.items().
- removal of 'from __future__ import' lines, which 2to3 changes into
empty lines; I removed the empty lines.
It's called on each extension after all extensions have been processed,
and after all built-in Pillar modules have had their setup_app() called.
Call order is random.
Refactor of pillar-server and pillar-web into a single python package. This
simplifies the overall architecture of pillar applications.
