title: woocommerce product "custom info input" field option
body: <p>I'm doing a WP site at the moment with woocommerce and want to be able to allow to customer to add information on the product order page that will come through with the order.
  The site offers slate engraved house signs, so I'd like the customer to be able to choose the product from the shop ie., a sign at say 300mmx200mm, then have the option to input:
  1 what text they would like
  2 what font (choice of 5)
  3 what colour (choice of 5)</p>
  
  <p>Once this is all in, they can proceed to checkout and the details come in with the order.
  Hope this makes sense :-)
  Is this at all possible?</p>
