Bug#243705: languagechooser: Do not use unnecessary "Choose this to continue in..." entries in languagelist

[Nikolai Prokoschenko <nikolai@prokoschenko.de>]

Package: languagechooser
Severity: important

The entries for the languages are just too long. This is unnecessary
and harming. For example, I have to scroll down the ru entry, read the
whole line to make sure it's really russian and not Bulgarian,
Ukrainian or Byelorussian, then understand the difference between ru
and ru_RU and the select. This must be more intuitive, for example

Russian (other) - Русский (другие страны) - ru

This would be enough to choose the needed language. It is understood,
that we will continue the installation afterwards.
