Title: Add note for assignee changes

Implements the feature as requested in http://feedback.gitlab.com/forums/176466-general/suggestions/5168130-record-assignee-changes-in-the-comment-timeline.

When an issue assignee is changed a note is generated. The note is italicized to match the status notes (reopened/closed).
