- added terse syntax to modules.rst
 - added description of special variables to template module

 - fixed template (it was the template), adding indentation with Jinja2
 - added description of code examples to man-page template (was missing)
 - fixed fireball, cron, and debug module examples to confrom

implement lookup plugins for arbitrary enumeration over arbitrary things.   See the mailing list for some cool examples.

Teach fireball mode to disable the fireball by paying attention to 'minutes=N' (default 30) and do not let fireball module crash
on input.

- amended

The very first start of 'fireball mode', which uses ansible in SSH mode to deploy a ephemeral zeromq daemon (entirely optional) that is will die after
it is no longer used.  No key signing will be required.  At this point, development use only -- NOT complete.
