New LC LOCALE picker dialog.
Add relevant strings.
Build LCLocale dialog.
Massive cleanup in LocalePage. Add LCLocale setting, with autodetect.
Load lcLocale value into GlobalStorage. Also allow localeGenPath setting
in locale.conf.
Write lc locale setting from GlobalStorage.
locale: Don't assume 2-letter language codes.

Some languages have 3-letter codes. So instead of splitting the output
of QLocale::name, use QLocale::language and the static
QLocale::languageToString.
locale: Optimize guessLCLocale by moving function calls out of loops.
locale: Support distributions without locale-gen.

If /etc/locale.gen (or the configured localeGenPath) does not exist,
assume that all the supported languages are already built into the
locale archive, and retrieve the list from "locale -a".

The list will then contain lines with only the locale rather than
locale + space + encoding, but that should not affect any of the rest of
the code. UTF-8 locales will still contain the string "UTF-8" (as part
of the ".UTF-8" suffix), we will not write a locale.gen file if we don't
have locale-gen, and everything else just strips away the encoding.
