Allow I18n hint_key to be customized to include custom variable and allow i18n in html format when specified.

[bekicot]

What would you like to be able to do? Can you provide some examples?

# config/locales/id.yml

id:
	administrate:
		field_hints:
			order:
				customer_html: "Id Pelanggan. Bila tidak ada, silahkan <a href='%{new_admin_customer_url}'>Buat Pelanggan Baru</a>"

How could we go about implementing that?

• In the dashboard, add a new method to expose the required custom variables

def i18n_variables(resources)
  {
    new_admin_customer_url: Rails.application.routes.url_helper.new_admin_customer_url
  }
end

• Update the view to reads from administrate.field_hints.resource.{field.html | field_html | field} ( assuming we are prioritizing the html version of translations`

Can you think of other approaches to the problem?
