Consider changing default color prompt to LightBG

[Benjamin Thyreau]

Hi,

As far as i know, all Linux computers sold those past years have default terminals background to some "Light" color. Most users fells happy with the default choice, and therefore runs into displaying "problems" when using the default IPython configuration from fresh install.
IMHO, It would help a lot if the relevant lines in "IPython/UserConfig/ipythonrc" were changed to default to LightBG, as power-users would have no problem changing the default to accommodate their dark screen.

And thanks for this great program !

I think the KDE konsole may still default to black, no? I'm not sure though, since KDE 4.0 came out I stopped using that disaster.

And in Windows, the default console (cmd.exe) is still black, that one I'm sure about.

In any case, we're currently massively redoing the config system, and it will be after this that we can address this problem more cleanly. I actually want to have this option be something that we ask users about at startup on the very first install. The reason is that this is pretty much the *only* config option we can't easily guess.

So what I want to do is, on first startup, ask the user about their preferred terminal background and set it accordingly, at the same time printing a message about how to change it again.
