hostname module: add support for Amazon Linux

Added a parameter for dest_port and also check ansible_ssh_port inventory variable.

Using
```
assert 'changed' in result
```
doesn't actually check if something is changed, which is presumably
the reason for the assertion. What is actually needed is
```
assert result.get('changed')
```
which checks that changed is set and not False. Tests still pass after
this change

Fix "manual" ansible-playbook example in guide_vagrant.rst

The given example is trying to load an inventory file with the -i option, so it should probably be given the actual Vagrant-written inventory file name. I contemplated using 'vagrant_ansible_inventory_default' instead (which is what my Vagrant demo actually creates) but 'vagrant_ansible_inventory_machinename' is more consistent with the existing example in the docs.

Add PyPi version badge.
