Bury it under the noise floor

The node.js port is not yet up to feature-parity with the PHP original. But it works for simple text strings. Most of the missing features are simple changes and fixes.

I would prefer to re-work the library into a more proper functional style, as it suffers from some of the style of PHP, as it was a more-or-less direct port. If there is sufficient interest at the github page, and/or bitcoin-sponsored issues, I will devote time to fixing them. PR's are always welcome.

In light of recent idiocy in government threatening to attack encryption, I changed the license to the most permissive license I could find.

I will not ration bullets in a war. Fork it. Mutate it. Re-purpose it. Learn from it. Make government impossible.
