Icon naming spec compliance:
remove network, in favor of network-workgroup (or whatever fits best).

This was the last icon naming showstopper bug (breaking interoperability with other icons that begin with network-*), which means that KDE apps won't break when working with other naming spec compliant themes, and Oxygen
doesn't break apps that solely rely on the naming spec.

If we're lucky, both of those should look pretty ok :D

There's more stuff that needs to be fixed (good times ahead!), but now I shouldn't be remembered as "the guy who broke the icons".

Now on to more cleaning up.
