function boolean_field_instance_settings_form in Boolean Field 7

Implements hook_field_instance_settings_form().

Initially build the form without the vertical tabs so that the instance settings form items are parented like instance[settings][true][prefix]. If we try to build it all at once, then the parenting is nested two more levels like instance[settings][state][tabs][true][prefix] and does not line up with the instance settings as defined in the hook_field_info().

Then use an #after_build handler to insert the fieldset and vertical tabs.
