Title: Fix code completion for not-supported languages on c9.io

Triggering code completion in files without snippets for the language completely fails because the cross-scripting restrictions trigger an exception in the browser when a file is fetched taht does not exist (the 404 does not set CORS headers). As a workaround, I've put a try-catch around the xhr.send() call. This should allow code completion to also work in Ruby, Python etc.
