Fix "Webbrowser" and "Device Informations" icons in TCC. #71

If you navigate from the kicker menu in the TCC submenus, you will notice that under "Internet & Network" there is some Konqueror icon used for the "Webbrowser" submenu. While that looks very good, this will not be shown if you open TCC and click on the "Internet & Network" link. In this overview page, you will notice that this icon is lacking. Instead of that, some generic, blank folder icon is used as some placeholder. That should be fixed to be consistent.

The same for the "Device Informations".

EDIT: Also, you can't click on that entry from this overview page, because it isn't some working link.

Good point. That "web browser" in the overview page should be a link and when clicked it should open the "web browser" overview page that is shown when clicking "internet & network" in the treeview on the left side and then on the "web browser" entry in such tree.

Same applies for the other submenus, for example Peripherals -> Information is another one. We should double check all submenus in TCC
