Refactor RateLimiter so that if Redis is not running, everything still runs normally (minus the rate limiting protection). My assumption that creating a Redis connection would throw an exception if Redis wasn't running was wrong. The exceptions actually occur when you issue a command. This is for #224.

tinyMCE.addI18n('en.autosave',{
restore_content: "Restore auto-saved content",
warning_message: "If you restore the saved content, you will lose all the content that is currently in the editor.\n\nAre you sure you want to restore the saved content?"
});
