Title: Fix #716, Allow column className to be a function

- A column's className property may now be a function or a string. If
it's a function, it will be called when the row cells are created and
passed the object being rendered in that row.
- Cells will always include the dgrid-generated "field-" class, even
if a custom class is specified.
- Changes to the value of an editor column after row cells have been
generated can be handled via a "dgrid-datachange" listener.
