default since "{{ None }}" actually becomes an empty string (there isn't
a way to set a variable to None/null from a template block as far as I
can tell).
defaults/main.yml -> vars/condition.yml -> tasks/merge.yml.
Properly templateize everything.
Move as much as possible to defaults to simplify tasks.
Munge stuff is broken, should be fixed soon, just wanted to get this committed.
