The new network tool got some GUI updates, mostly about widgets sensitivity. It now allows to set up basic authentication data (login, password) for ppp connections (POTS and xDSL modems).

I'll try to move most of the common stuff about ppp connections in the new network::ppp module, this includes configuration files management, but also listing the required authentication fields. These fields are meant to be used by interfaces, so I've used the same data structure that in the interactive module from DrakX (which doesn't depend on specific interface code).

This way, it could be re-used in our other network interfaces, factorizing again the code. Our current network tools (wizards and some Gtk2 programs) already use the interactive layer. Unfortunately, it's not currently possible with interactive to add Gtk2 widgets in an existing window, so my first draft reimplements (big) bits of this module. But, hopefully, it will get fixed next week!
