Compile to web browser (WASM-pack?)

[skyl]

What

Compile library to run on browser

Why

Would open up a ton of possibilities for easy developer ergonomics if vanilla webapp in the browser could call lightwalletd.

Hah... that wasm branch has moved a very similar subset of the code I was hacking on in a local experiment..
Basically the lightwallet directory. Great find! Thanks.
