The Facter library is no longer 'required' anywhere now that Puppet is no longer loaded due to #2414, but we still have quite a few references to it.

This causes DB migrations on a clean installation to fail:

uninitialized constant AddOwnerToHosts::Facter/var/lib/workspace/workspace/test_develop/database/mysql/ruby/1.8.7/db/migrate/20100419151910_add_owner_to_hosts.rb:12:in `up'

Other uses of it:

app/models/setting/auth.rb
app/models/setting/provisioning.rb
app/models/setting/general.rb
lib/tasks/reset_permissions.rake
db/migrate/20100628123400_add_internal_auth.rb
db/migrate/20100419151910_add_owner_to_hosts.rb

All of these should probably just require 'facter' until we can get rid of it too.
