Fix TODO comments about D6->D7 conversion of database syntax

./submodules/fbss_comments/fbss_comments.pages.inc:105:  // TODO Please review the conversion of this statement to the D7 database API syntax.
./submodules/fbss_comments/fbss_comments_flag/fbss_comments_flag.install:15:  // TODO Please review the conversion of this statement to the D7 database API syntax.
./submodules/fbss_privacy/fbss_privacy.module:26:      'description' => t('TODO Add a description for \'send private status messages\''),
./submodules/fbss_privacy/fbss_privacy.module:30:      'description' => t('TODO Add a description for \'view all private status messages\''),

There are more than this, but I've removed the ones that don't need to be addressed in this issue (e.g. in other submodules that haven't been properly ported yet).
