Previous and next wave front selection buttons on the top row do not update the wave front list correctly.

Those left and right buttons at the top are suppose to step through the wave front list. Selecting one and causing it to be displayed. An icon moves at the front of the list to show what is selected but that item does not highlight as if selected and that wave front is actually not what gets displayed.

Load 2 different wave fronts and try it out. At least for me it does not work. The display changes when you press a button but then if you actually click that wave front it changes the displays to the correct one.

In addition it probably would be nice if you could use the up and down keyboard arrow keys to the same thing. Currently they move the selection but do not update the display.

I think this whole wave front selection logic could be improved and simplified if the wave front qlistwidget listened for current item changed signals instead of clicks on the item. Currently the top buttons trigger code in Main window that then calls surface manager. Perhaps they should talk to the list widget instead. The list widget is in the surfaceanalaysestools class and mainwindow should know it.

I have made the changes. It was very simple and reduced the complexity of the code. I will test it for awhile.
