Removes koRunElevatedInVista, koSwitchLanguageForAllApplications,
koSwitchLanguageWithKeyboard, koUnknownLanguage, koTurnOnSurrogates
from localizations and from UI.

These options are no longer relevant, mostly due to improved operating
system support.

Only one option was still visible, koSwitchLanguageForAllApplications,
so this has been hidden in keyman_options.xsl, for future full removal.
