title: Magento lowercase all product titles
body: <p>For some reason, my client added all products with capital titles in their Magento shop.
  Now, I'm redesigning their webshop and I don't want to have capital titles.</p>
  
  <p>I'm thinking about running a script, that's replacing all product titles for lowercase titles in the database. But, I'm afraid to ruin the database. </p>
  
  <p>Does anybody know, how I can do this properly? </p>
