Multilanguage support

[adam-m]

Various contributors have offered help in translating, but we need to add support for this.

• localize all user visible strings
• make sure branding and multi-language support work well together (different versions of Bundle.properties)
• cleanup all Bundle.properties - remove unused strings (write a script or use existing tool)
• document how to translate (which files to provide, etc)

For completeness, I'm copying in the message that I sent to the users list yesterday on this topic:

The basics can be found here:

That being said, we know the following:

• There are strings in the bundles.properties files that are no longer in the UI. We need to clean those files up so that only the needed strings are translated.
• Not all strings made their way into that file. So, we need to externalize some of them.

Most strings are currently handled through bundle.properties and we have JA localization.
