Updated - server-side processing support for camelCase variables

- As part of the 1.10 move to camelCase the server-side processing
  return now accepts camelCase variables as well as the old 1.9
  hungarian notation.
Updated: Rewrite of the PHP example server-side processing script

- This is far from finished in this commit! However the basic move it so
  use PDo with more arrays rather than string manipulation to try and
  make things cleaner. This needs a good deal more work before I'll be
  happy with it, but it does work for the simple example now

- Examples updated to output the SQL needed based on the source data
  file.
