Improved Asian Languages Support

Three things of note happened this week:

First, many thanks go to the efforts of the Shanghai Library, which has provided us with the text for a Chinese localization of the LibraryH3lp chat widget.

Second, we've made some enhancements to the admin UI, so that it is now possible to register new admin accounts, as well as create queues and users in non-English languages. *EDIT* Earlier I stated that it was not possible to login to the webchat client with a non-English username. That problem has been corrected.

Third, we're now hosting the widget on servers in Hong Kong and Tokyo (in addition to existing servers throughout the US and Europe), thanks to Amazon's new Cloudfront service. This should provide better load times and performance for Asian users.
