Merge branch 'upstream/master'
Updated server to simply give a suggestion. This is the only current requirement with the new client side code, and Simple is Good.
Removed now unneeded hackapp JS
Tidied up and simplified CSS
Refactored front end to use MVVM via knockout JS. This severely simplifies the application. As a result, the user experience has also become more responsive. Input is watched and acronym suggestions are fetched as available.
