Title: Adjustments for ARIA compliance

* The Enter key is now a valid activator for sorting columns
* The Enter key is now a valid activator for selector-based checkboxes
* Each dgrid row now has a role of "row" instead of "gridcell"
* Each dgrid cell now has a role of "gridcell" instead of no role

Also, looks like my editor got a little aggressive with cleaning whitespace at end-of-line.
