If you click the sections in the left side treeview, some of the
elements in the right page headers will move a couple of pixels.
Also, since the WPAD warning label was always visible, the alignment of
the controls section in the Proxy page was suboptimal.

In bug 689638, the designers only asked for the list icons
to be symbolic, not the big icons in the page headings. The
current code was failing on both ends: virtual devices like
vlan still had non-symbolic icons in the list, and several
pages (e.g mobile and proxy) had symbolic icons in the headings.

This is consistent with the guideline to use symbolic icons for
classes and reserve full color icons for "things" like apps, people,
documents, pages, etc.
It is also consistent with how these devices are displayed in the
network menu, notifications, and dialogs.

A source file with 4k lines of code is not understandable, and the glade file
was becoming quite a challenge for glade.
To add more features we need to split things up just to keep them maintainable.
This is the first patch that just splits out the proxy bits. Other device types
will follow in the next few days.
