Because responding to a CTCP request is completely optional,
sometimes thelounge will just do absolutely nothing. (the request
was received, but the client did not respond to it)
This alleviates the problem by always notifying the user that
*something* was sent.
This is a Node v6+ only fix.
`irc-framework` upper-cases the first argument, and we were sending everything as a string in first argument. This correctly splits.
Several ES6 additions are only available in strict mode. Example:
> SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode
Strict mode was also enabled in a few of our files already, and it is a good thing to have anyway.
