RFR: 8213716: javadoc search not working with Japanese and Chinese locales

[Hannes Wallnöfer]

Please review:

Issue: https://bugs.openjdk.java.net/browse/JDK-8213716
Webrev: http://cr.openjdk.java.net/~hannesw/8213716/webrev.00/

Note that I removed the localized messages for Types, Members and SearchTags categories as they aren’t used anymore (they were never used to display these categories to the user). If we want to use these localized messages for search categories (as we probably should) I’ll file an extra issue for this.

Thanks,
Hannes
