Both approaches now use a pillar.auth.UserClass instance. g.current_user
is now always set to that instance, even for web entry points.
This UserClass instance can still be keyed like the old dict, but this is
for temporary compatibility and shouldn't be relied on in new or touched
code.
Refactor of pillar-server and pillar-web into a single python package. This
simplifies the overall architecture of pillar applications.
