angstrom-2007.1.conf: Ship just en-gb locale by default.
* Ship just basic locale by default. Locales are big (~1Mb uncompr.), so
shipping some adhoc subset will be still useless and size burden for
users of all other languages/countries. Instead, worth to make it easy
to install additional languages: installer/wizard + metapackages which
will RRECOMMEND as much as possible content for a given language
(locales, UI transalations, help, etc. - useless for pros, but really
helpful for common users).
