Add multi-trace support for select information window

These commit move the select info window to be an attribute in RenderLayout.

Thus, there is one SelectInfo for each trace.

In each SelectInfo window there is one or two buttons to center the trace on the beginning or the end of the selected entity.

One small "bug":

1. open a trace
2. click somewhere to open the information window
3. close the trace => the information window is not closed, while I think it should be
