Qt: Add Time and Comment labels to the sequence diagram.

Add "Time" and "Comment" labels to the sequence diagram similar to the
GTK+ UI. Draw a border around the diagram as well.

Widen the default spacing and set it to a simple em-width multiple.

Fix our port number alignment.

Copy over the sequence diagram colors from the GTK+ UI and add them to
ColorUtils. Color sequences according to their respective conversation
numbers.

To do:
- Add zoom.
