Signature lists/comments now publicly available

Gopetition has now integrated a public signature list feature into all petitions. This feature is turned off by default, but authors now have the choice to turn this new feature on to show the signatures and comments of their petition signers. New signatures will have the option of displaying their signature publicly (note no email details will be displayed). Signatures collected before this feature was implemented will automatically be kept private, the feature will only affect new signatures.
