Improvements

not aiming for perfect but could be better in these ways:

• Turn SQL in .sql files to stored procedures instead of or alongside being auto-invoked
• Switch to better logging, something like:

   import java.util.logging.Level;
   import java.util.logging.Logger;
   Logger.getLogger(EshopDatabase.class.getName()).log(Level.SEVERE, null, ex);

• Check todos in code
• Find way to store product images in database
• use sql custom mapping
