Feature: Disable first option in dropdowns.

[marvin-martian]

As a feature: allow the first option in the a country/region select to have the disabled attribute set. This would force the user to make a country or region selection, and not allow the user to select the options "Select country" or "Select region". See an example of a select with the first option disabled: http://jsfiddle.net/s5Xy2/5/ to get the behavioural idea.

<select class="crs-country" data-region-id="region" data-value="shortcode"  data-crs-loaded="true">
    <option value="" disabled="disabled">Select country</option>
    <option value="AF">Afghanistan</option>
    <option value="AX">Åland Islands</option>
    <option value="AL">Albania</option>...

<select id="region">
     <option value="" disabled="disabled">Select region</option>...
