Insert query strings as temporary cache hack

Insert query strings as temporary cache hack

Once we deploy Benji's cache header GUI charm upgrade and make a release with the index.html hacks, we can take the query string silliness out again.  Meanwhile, it is a cheap way to try and get updated files before we get the headers in place.

The "sprite" -> "sprites" is another silly way to force a reload, but we can keep that one <shrug>.

This also includes commenting out the recent SASS changes, because they could not be built in the charm.  It looks like the charm needs to add g++ as a build depedendency too.

Please take a look.

LGTM assuming the npm stuff was automatic/generated. I think this helps make the
case for the pyscss usage. It sure seems the node stuff has caused us more
grief.

Code LGTM.

Code LGTM, thank you Gary!
There is a problem with the internal Python server not being able to serve
correctly static files if the URL includes a query string.
As a consequence, the GUI does not work well when run with make debug/pro.
I am fixing this and then I'll land this branch.

Landed, see https://codereview.appspot.com/12335043/
That branch includes the Python HTTP server fix.
