Implement bulk uploads for organization tasks.

We add publish and unpublish buttons to the organization tasks list
for org admins and use the POST data that we receive upon clicking
those buttons to process it and publish or unpublish the task.

Note, that list_config.addPostButton call also enables the per-row
checkboxes on the list.
