One can now select a packet and mark it as a TimeReference packet using the menu. A TimeReference packet will be indicated by having all timestamp related column entries replaced by the string *REF* A TimeReference packet will always be displayed in the packet pane, and overrides any display filters. When a frame is a TimeReference frame, all later frames will calculate the TimeRelativeToFirstPacket relative to the timestamp of the TimeReference frame instead of the first frame of the capture. You can have any number of TimeReference frames you like. svn path=/trunk/; revision=8459
