[support] Changing checkboxes options during hook_node_validate

[Jamie Holly]

There could be something else overriding that in validation. Instead of 
using the default hook_node_validate, trying adding $form['#validate'][] 
= 'my_custom_validation_function' in hook_form or hook_form_alter. That 
way it's the last validation hook called.
