Bugfix #915. Removed autosorting on afterChange, afterRemoveRow and afterCreateRow. Added method sort(col, order) that enables to trigger table sorting programmatically.
Bugfix #895. Added ability to check/uncheck checkboxes using spacebar.
Added beforeColumnSort and afterColumnSort events fired before and after performing table sorting, as requested in #931.
Handlers for both events receive two arguments:
 * column index
 * order of current sorting.
