Remove appcache

Remove appcache

The HTML5 Application Cache will no longer be pertinent with upcoming design changes.  Additionally, it was causing the site to fall over in various ways as time passed or after the config-changed hook was executed.  This MP is sort of "half WIP", as the QA aspect will take some time to observe.  To that end, I've set up a QA instance at https://ec2-54-243-27-37.compute-1.amazonaws.com/ that we can keep an eye on and play around with.  If things look good as compared to http://tinyurl.com/jujucharms, then we can consider landing.

Please take a look.

Code LGTM.  Ack on the QA; sounds like a good approach.  I'll reply back if I
see any related problems.  Thank you!

LGTM

I thought the plan was to conditionally remove this on debug builds, but it
seems fine given the very limited savings I heard on the call.

I suspect we might revisit this as I'd like to build a version that was a
Packaged App with the sandbox on that people could install with a single click
and being playing with the ideas around juju.
