* Give a type to networking.interfaces.
* Simplified the pre-start script of the network-interfaces module. * Removed wireless support from the network-interfaces module. It only worked for static WEP configurations anyway, and AFAIK nobody used it. svn path=/nixos/branches/modular-nixos/; revision=16406
