documentation should be fixed

[WianVos]

We need more documentation on the various parameters of the module.
Because read the fracking code is just no gonna cut it

[ltutar]

also one errata:

xldeploy_ci{ "Infrastructure/projectx/${hostname}_sshHost":
ensure => present,
type => 'overthere.SshHost',
properties => { 'os' => 'UNIX',
'port' => '22',
'username' => 'deployit',
'tags' => 'projectx',
'connectionType' => 'SCP',
'address' => '${hostname}' },
rest_url => 'http://admin:password@xldeploy.domain.local:4516/xldeploy' }
}

Here the line with 'address' => '${hostname}' }, should be 'address' => "${hostname}" },
otherwise the hostname will not be resolved and put in XL Deploy as ${hostname}
