Content Type variables not required to be exportable.

Hi,

In current feature, many content type settings variables are added which are not required to be there in feature as per my understangs.
e.g.
'node_submitted_advanced_page' variable is set to 1 in feature. But if any user disable 'Display author and date information' option, feature state will change to overridden. If we want to make it general, we should remove such variable from feature.

Variable list that we can exclude from feature.
menu_options_advanced_page
node_options_advanced_page
node_preview_advanced_page
node_submitted_advanced_page
comment_advanced_page
comment_anonymous_advanced_page
comment_default_mode_advanced_page
comment_default_per_page_advanced_page
comment_form_location_advanced_page
comment_preview_advanced_page
comment_subject_field_advanced_page

Thanks,
Omkar
