means ln and os.rename() won't work across fs.

Both modules seboolean and zfs have not been adapted since they defer from the default (either by having a 'null' or special state, or prefering "on"/"off" for state indication.

Fixes #2165.

  - added cron_file attribute: if specified, the file with appropriate
job is created in /etc/cron.d directory. Also, you can store multiple
jobs in one file. state='absent' attribute is handled in the following
way in this case: if after the deletion of the job from the file specified
by cron_file variable the file is empty, the file is deleted, otherwise
not.
  - fixed the behaviour, when the backupfile is saved forever in /tmp
folder, even if the backup= atribute is not set (os.unlink() is called if
backup is not True).
  - added some comments to the unobvious places

This updates apt, apt_repository, command, cron, easy_install, facter,
fireball, git, group, mount, ohai, pip, service, setup, subversion,
supervisorctl, svr4pkg, user, and yum to take advantage of run_command
in module_common.py.

Fixes #1787.

Added error message when reboot and extra params are passed, and added better boolean parsing on reboot

 - added terse syntax to modules.rst
 - added description of special variables to template module

 - fixed template (it was the template), adding indentation with Jinja2
 - added description of code examples to man-page template (was missing)
 - fixed fireball, cron, and debug module examples to confrom
