	testing YAML in YAML: small glitch in rst template; a </pre></p> is outdented and causes messy display

Added documentation to APT module

Fix to make sure only strings are being joined

Module DOCUMENTATION for template, wait_for, and yum

Module DOCUMENTATION: assemble, authorized_key, command, copy

Close zeromq context and socket.

  plus a small fix in rst.j2 template
  manpages generated & checked
  modules.html generated & checked

Since BOOLEANS also contains integers, joining the list returns an error. Easy to test by giving a wrong value to a boolean argument:

    service name=httpd enabled=True

Since True is not in the allowed BOOLEANS, it will cause the error, which in its turn bails out because it joins strings and integers.
We may want to remove the integers from the choices since '0' and '1' are already in the list as strings. Personally I would expect only strings as arguments, not sure where these could be integers ??

module_formatter fixes

Revert pull request #1091

Automatic quoting of variables in only_if breaks existing playbooks
where entire statements are put in a variable, and other cases. See
issue #1120 for details.

Various tweaking to get the module formatter to work for 'make docs' in the docs project.  Likely the templates for other module formatting types will have to change
by the time I'm done.

Revert only_if for variables and templating prompt, little practical use

Since the condition was not templated, it wasn't working.
Only variables in local scope were used, which made this not very practical

New module: manipulate INI-style settings

This fixes a few issues,
- ${foo}${bar} would be parsed as a variable named foo}${bar,
  which wouldn't be easily fixed without breaking ${foo.${bar}}
- allows escaping . in variable parts so e.g.
  ${hostvars.{test.example.com}.foo} works

This is slower than using re. 3 million templating calls take about
about twice as long to complete with this compared to the regexp,
from ~65 seconds to ~115 seconds on my laptop.

Fix only_if statements referencing non-string types

Remove assemble action plugin, fix daisychaining

Strip trailing white space from $FILE()/$PIPE()
