Added missing destructor for transaction window object.
Started constructing list of UI elements for ports.  Need to make a class to display port data.
Added skeleton UIPortData files.
First hack at a working set of UI widgets for the ports.  Still missing text setting functions in UIPortData, but besides that everything is here.
Added ways to set the rum and gold displayed by the UIPortData UI element.  They display the actual numeric amount of rum or gold followed by an R or a G, respectively, to indicate which amount is which.
