Makes ports configurable for fireball.  Note port defaults really belong in the connection plugins, not runner, which can be refactored later.

Various small fixes to boolean usage and defaults

cron feature (w/o tests)

Keep the man3 directory. 'make docs' breaks without it.

Add this module's namespace to the 'module_' namespace.

Fix typo in service module docs

Add inventory variables for hosts not in the play to hostvars.

Look up only when requested and cache the result.

Much like we currently have *setup* register the variable `module_setup`, we would like other facts-modules register their own namespace. This means that:

 - *network_facts* registers `module_network`
 - *hpilo_facts* registers `module_hw`
 - *vsphere_facts* registers `module_hw`

In retrospect, it would have made more sense to have `setup` register `module_ansible` instead as the setup module uses the `ansible_` namesepace.

Having the `module_` namespace allows us to check whether a certain namespace has already been loaded so we can avoid running the facts module a second time using only_if.

```yaml
 - action: network_facts host=${ansible_hostname_short}
   only_if: is_unset('$module_network')
```

chapter 3 manpage source does not belong in git because it includes datestamps that constantly change.  Willing to re-add if datestamps
are removable.

Fix typo/cosmetic change

Vsphere facts fixes

This is the opposite as library/virt, but much better than using name= as the default option name.

Module hpilo_boot to boot from specific media using an HP iLO interface

Not for cow lovers: optionally disable cowsay

spaces now cow-compatible

This module allows to boot a system through HP iLO and can be used to start the provisioning process.

fix examples in hpilo_facts DOCUMENTATION

Added a ANSIBLE_FORCE_COLOR env var, which forces the color output

fix wording of shell documentation
