Add encoding lines to python modules such that they can take unicode options if they are fed them, since the
AnsibleModule stuff no longer base64 encodes for simplicity and speed reasons.

Port the file module over to the new common code infrastructure + cleanup some redundant imports since the module code already imports those things.

Save the transfer of the module file for new style modules, because we can inject the arguments into the modules.

Module consumers using the API don't have to know how this works.  base64 stuff is only there
because escaping a docstring inside a docstring was a bit of a challenge :)

The ohai and facter modules use /usr/bin/logger to log the fact that
they have been invoked.  I added 'import os' to the ping module
so that it could have the same syslog statements as the other modules.
I separated the condensed:
    shlex.split(open(argfile, 'r').read())
into two separate statements similar to the other modules.

still needs to daemonize.  Then, once done, playbook can be taught how to poll async within the
timing window.

CentOS5 has python 2.4 which doesn't have a built-in json
module
