Title: [IZPACK-1144] - New button field

This is to address http://jira.codehaus.org/browse/IZPACK-1144
Button fields allow the user to optionally run a custom action or validator.
A use can for this could be for testing a connection to a service (ldap, webapp).

Allows you to specify the label with the id attribute from the tags.
Allow you to specify the text on the button with the id attribute from the tags.
Allow you to specify a success message if the custom action/validator ran successfully with the successMsg attribute in the tags.
Allow you to specify messages available to your custom action/validator in tags nested under the tags.
```

```
For an example experience please see the references Jira issue above for instructions of building a sample installer.
Documentation will be updated if looks good.
