Prevent stale resources (esp. JS + CSS) from being cached across releases #848

We have occasionally frustrated users (and testers) when they fetch a fresh version of the web apps, but their browser has cached an older/incompatible version of JS or CSS files. Here are some ways to address this:

  1. add a query-string with SHA or timestamp (changes with each deployment)
  2. move caching to a smarter server-side cache
  3. use a "conditional get request" with an If-Modified-Since header
  4. if (1) above defeats all browser caching, munge the path instead (site/v4.3/myScrips.js)

@jar398 suggests investing etags as the sensible solution here
