We were observing UI jank, which ended up being due to GC. Even with chunking
and very small chunk sizes, it was hard to reliably get 30fps on my macbook.
Moving to a worker completely solves the problem. We stay at 60fps the entire
time the hashing is taking place, no matter how many files/how large, etc.
Also, switch to using Closure's crypto support, which has been added since
the upload code was originally written, since it hassupport for incremental
hashing, javascript typed arrays, and other niceties.

1) Everything in ui/ except for js-notes.txt was removed.
2) mv newui/* ui/
3) modified pkg/server/ui.go to make it all work
4) modified Makefile to generate server/camlistored/ui/deps.js
5) regenerated all the zembeds
6) Some fixes to attempt to make it (re-)work on appengine:
-removed the Go1.1 check
-added pkg/osutil/restart_stub.go (for restarting a process)
7) The closure handler now redirects to the online files when
the closure library is not on disk, because we do not embed
the required closure js files.
