Enabled repositories in default install

[retype]

I think a first start message is really needed, and it would be better
if we use rosetta to translate it. I always have to spend half an hour
or more with every new ubuntu user so I can explain how to put
universe, how to install mp3 players and everything that is need to get
a full working system.



Maybe we need that and changing the icon of synaptic for something more
apropriate, like a litle ubuntu certificate or something like that. A
debian swirl next to an application doesn't say anything to a normal
user (specially for one that doesn't even know that ubuntu is somewhat
related to debian).
