Adding strings to re3's GXT, recompiling GXT files

- Adding the Radio Off string (thank you!) to the Spanish translation.
 - Added translations for the new languages to the French/German/Italian translations (using WordReference, no automated translation) as well as the Radio Off string (taken from LCS's official translations and uppercased). It's a bandaid, I know.
 - Recompiled the GXT files. Russian will probably have differences, but since the last recompilation was rejected because of Russian, I've removed its binary version.
