Clone Checklist when Issues Are Cloned

Cloning checklists for cloned issues works out of the box. Statuses of cloned checklist items are set to unchecked/open.

Note that cloned checklists take precedence over default checklists and Checklist Text field content. For issues cloned with a non-empty checklist, neither the default template nor the checklist from the Checklist Text custom field will be applied.
