Implement urlArgs feature for cache busting AMD modules

[ryan-blunden]

• Server is telling client to cache files forever (good production practice)
• Client AMD module changes
• Client needs to alter the request path in order to cache bust
• There seems no way to do this currently via Curl

RequireJS provides this - http://requirejs.org/docs/api.html#config-urlArgs

Hey @ryan-blunden,

Wire doesn't do any module loading itself, but rather simply relies whatever loader is available in your environment. So, it seems like the best thing to do here is to file an issue over at the curl repo, and we can work through it there.
