Allow transport on tasks, and use it for local_action

This should help facilitate playbook decision making that are not
strictly distribution specific, but more package manager.

Atomic copy2

Make get_url module always return dest. 

add logrotate config

The url_get module now includes the destination in the returned JSON.

The check for the destination being a directory is now done before
checking if the file exists, that way the user is informed that the
thirsty argument is required.

this patch add current user (usefull where user have some different projects) with the oreder:

Previously, importing a playbook in a different directory didn't

the top-level playbook.

This patch resolves relative paths on a per-play level instead of
relative to the directory of the top-level playbook.

Also removes the dirname argument from the Play._get_vars method
since this argument wasn't used in the metho dbody.
