Add an item tracer to the TCP stream graph. Enable packet selection.

QCustomPlot data sets are made up of keys (x axis by default) and values
(y axis). It looks like we can have multiple values for a given key
(i.e. we can show multiple sequence numbers for a given timestamp) but
QCPItemTracers can only be positioned by a key and not a key+value pair.
This makes our graph selection behavior a bit different compared to the
GTK+ version. We can only select one segment for a give timestamp but
our selection targets are much larger (the height of the graph).

Add a map for segment data so we don't have to iterate to find them. Use
UTF8_RIGHTWARDS_ARROW where appropriate. Set a window title. Tell the
user what will happen if he or she clicks. Disable graph selection.
