yum module fix - catch more errors

catch all exceptions and emit sensible errors - if we have a config file error this lets us know about it

Eliminate possible race condition in async_wrapper where ansible deletes the argsfile while the module
is still kicking off.  Should not happen except in modules that are somewhat slow to load and probably
can be fixed better than the included sleep, i.e. some IPC communication that the process has
launched and is ok to exit.  This works pretty well for now though.

Run tests in verbose mode.

Stderr logging

Make copy module idempotent.

Check md5sum before overwriting a file. Unconditionally copying changes the timestamp.

Correct default user and port in playbook.

d would be useful for --dry-run.

This prints remote module stderr on local stderr.

This prints the stderr of the executed modules on local stderr.
Most methods on Runner now return a fourth "err" parameter.

They are set in the constructor.

Conflicts:

	lib/ansible/playbook.py

Removed unneccessary shlex and replaced with basic split, some repurcussions in runner
that can be eliminated once we consistently pass args as a string (soon).

(edited author's original commit comment -- MPD)

support for quotes strings in command module (via posix=False), related fixes to keep other things from breaking

Fix except statement in template module.

Python 2.4 (RHEL 5) does not know 'as'.

Sudo support operational in both playbooks and main program.   Implementation could use some cleanup.
