Dev: Little tidy ups from the previous merge - mainly just whitespace
Significant update to AutoFill:

- No global variable - must be accessed using $.fn.dataTable.AutoFill
- read, write and step functions for columns must simpiler
- Full compatiblity with 1.10 and leverages the new API where possible
  (1.9- will still work as before though).
- complete callback is made indepedent of columns
- Ability to provide defaults
- camelCase notation to match 1.10
