updated to correct to_bytes function
removed old to_bytes/to_unicode and repointed clients to new location
fixed unicode test

This filter was made because I needed to create idempotent UUIDs when
installing the agent for Go (http://go.cd), which uses UUIds to
distinguish the agents from each other.

It uses a newly created Ansible namespace to distinguish UUIDs created
by Ansible from any other source. The new namespace is a random one
created by uuidgen on OSX.

This 'mostly' reverts commit 2769098f.
