Add filter to turn a string into a UUID

Browse Source 
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.
