Ok, here is are the modified "mainwindow.*" files. The GUI is now on a
grid layout with spacers (I.E. the user can now resize it with
impunity), I removed the unneccesary bar, and I added a button to open
the freshports.org page for the selected port. I wrote a quick check to
make sure a port is selected for the port_info_button, but I did not
actually have it open a web browser. The function to add that capability
to is at the bottom of the mainwindow.cpp file.
Oh, I also fixed a bug on quitting that caused a "bus error" on exit.
(see the destructor for mainwindow)

Let me know if there is anything else I can do for you!
