But... I did just run into another thing

Suddenly, the seed stretching when creating a new wallet doesn't start at all.
Progress bar stays on 0 and nothing happens. Not sure if this is something
with my browser data or something, I couldn't further investigate yet.
Ah, that was because I got a little too eager deleting code from lib/bitcoinjs. Should be fixed with 0.1.6. I'll go through it (and other parts) more carefully to cut down the size of the package.
