Soycode jsrefactor

This is a typescript->JavaScript refactor, also addressing these issues:
https://github.com/freedomjs/freedom-pgp-e2e/issues/9 (eliminate uproxy-lib dependency)
https://github.com/freedomjs/freedom-pgp-e2e/issues/10 (update to freedom 0.6)

Additionally the demo is now a general freedom app and not a chrome app. That said, it's actually failing in Firefox right now due to an end-to-end error:
"Module Failed" Object { isTrusted: true } freedom.js:1291
Error: Seed is too small. end-to-end.compiled.js:231

I still think it's worth merging as I know other people are interested in looking at crypto code and this is definitely a better starting point. I'll look into the Firefox issue but given that the error is happening on the end to end side the fix may not be in our codebase.
