- support of [Strings.LanguageID]-sections for inf-files added in setupapi

- inf-files with multi language support are strongly recommended to be in utf-16 encoding (with byte order mark)
- at the moment only inf-files for second stage setup can contain translations (due to limitations of inflib)
- some of the inf files for hardware installation (/media/inf) are converted to utf-16 and contain a basic German translation in the [Strings.0407] section
- for more details read /reactos/branches/matthias-i18n/media/inf/README
- TODO: for other/further languages add other translations in new string sections
