[lokisetup] localization?

But sleep helps immensely: how's this patch:
    http://cvs.icculus.org/loki_setup/detect.c?r1=1.70&r2=1.71


If you specify a portion of the localization, it'll consider it for the 
matching. If you don't, it won't. So if you do "fr.utf8" it'll match 
someone with "fr" or "fr_FR" or "fr_CA.utf8 at blah" but not someone with 
"fr.latin1" ...

So most people will use this like they always have: <eula lang="fr">, 
but if you need to force a non-utf8 encoding, or customize for a 
territory (fr_CA, etc), or both, you can.

I don't think this needs a seperate "encoding" attribute in the XML tag, 
since it would require updating lots of places (eula, readme, other 
places) and the thing we're comparing against encodes the encoding type 
in the string anyhow, so keeping them paired makes sense.

I haven't touched anything in the GTK code to convert to/from utf8...all 
the data we're shipping is in UTF-8 format at the moment, so I don't 
really care further at this moment.
