This fixes #611.

Plays and tasks now yell when they see parameters they do not understand, so that typos like 'var' for 'vars'
don't result in people having to ask questions about what is wrong with their playbook

meaningful messages if the remote md5 fails

    First pass of the Ansible EC2 inventory script

Fix for the way host variables were being swallowed, plus some overall simplification.   Deciding what
dictionary to use for templating now happens in exactly one place (executor_internal) and the "inject"
dictionary is passed to what needs it.

format fixes to output from fetch

with_items handling code should apply to all modules, was screwed up in refactoring to only apply to 'normal'
modules.

Misc code cleanup, mostly whitespace preferences, removing unused imports, plus a few fixes here and there.

No need to feed variables into the setup module for preservation since the file is no longer saved to disk.

the setup file to disk.

and with_items incompatible.  Most cases that would need this could be solved
with vars_files.

you aren't going to need it.

Change the way we do with_items to make them happen next to each other in runner, which eliminates the problem of with_items and vars_files sometimes not playing  nice with each other.

(Also a fix for the user module error handling when the user
is not present at the time of the return.  This can only really be caused by multiple ansible executions).

Error handling and magic around with_items, to let you know when variables are usable inside it and when not.

Make the logic behind vars_files smarter, so host specific vars go into the setup cache, but other variables
are usable top level.  This allows vars_files data to be used, most of the time, just fine in with_items,
(error handling pending) but is mostly a memory and efficiency thing.
