Remove wireless network support from default install

Default install should be absolutelly minimal. And packagas shouldn't be dependent on stuff not needed.

For example:

Why, oh why "system-config-network-tui" requires "crda, iw, python-iwlib, wireless-tools"? When was last time you had a wireless interface on the server? It's not Fedora.

There are plenty of other examples. Current dependencies are broken and they need fixing.

Thanks
