update from vhcs

[dabdab]

After migration from vhcs, the default language is "unknown" everywhere.

Found this in "vhcs2.4.7-ispcp.sql":
-- English Translation is up to date after install
-- DROP TABLE IF EXISTS `lang_English`;

Yes, the lang_English is installed by "ispc-setup", but overwritten by the old table form vhcs2 by the "ispc-update".

May be it is a good idea to drop the `lang_English` too and reinstall the "good" `lang_English` form ispc later in the script?
