Josep Piguillem 285bd5c454 feat: what is new since my last visit, and turning a comment into a ticket
Opening a ticket notes the visit and answers the one before (issue_visits),
so the page marks others' comments and changes since. A comment can become
a ticket of its own, as a subtask or linked; it remembers where it went.
