Tidy Names and Postcodes Entered at Checkout
Cleans up what customers type before the order is saved: names get proper capitals, postcodes become upper case and stray spaces are removed.

Names typed in mixed case, such as "McDonald", are left as typed; only all-lower or all-upper names are changed.
