AutoComplete validation requires a global variable

[adamliptrot-oc]

When instantiating an autoComplete instance, you currently need to supply a global js object containing all the data for the suggestions to the validator. This is currently done via a data-suggestions attribute on the autocomplete html.

We should look at alternative approaches to pass this data back to the validator.

As discussed the need to have this on the host window object can go and this can just be sent in as an object via the data-suggestions attribute
