Email form on Block doesn't work correctly

When using the block feature the email form does not show up when you click on the tab because there are multiple forms with the same id (share-form). This is because of the fact that if the block is showing the Share link then there will also usually be another share link at the bottom of the node. Since both nodes have the same email form it breaks when you try to show the form in the block. Best solution would probably be to give each form a different id and update the javascript accordingly.
