Automate GDS style '(optional)' on titles

[ekes]

Just that. It'll add '(optional)' to the titles of elements on a webform that are not required.

To test use the branch, and then go to /admin/structure/webform/config and check the Third Party setting

• Expected behaviour (optional) added to the titles of elements that aren't required. Will also work with conditionals.
• Undesirable behaviour to look-out for: there might be elements that need to be excluded from the automated change (at the moment this is single checkboxes and radios, and every element of an address if all elements are optional -- but there might be, probably are, more we want to exclude).

Closing this in preference to the drupal.org one because well there's the up to date code.
