Title: Inject variables in growl server message

This pull requests adds a '_messageVariableKey' which allows you to inject variables in the server messages.

E.g. if a field is required the message could be:

````js
{
messages: [{
text: "{{field}} is a required field",
variables: {
field: 'First Name'
}]
}
````
