hook into beforeDelete()

I'm not able to hook into beforeDelete() model callback. I saw at the code of this plugin that you are doing this:

/**
* Intercept calls to delete and soft delete instead
* @param  Model   $model
* @param  boolean $cascade Cascade delete to associated models
* @return boolean          Always false so record isn't properly deleted
*/
public function beforeDelete(Model $model, $cascade = true)
{
}

Maybe we need to change this behavior?
