Move the undermaintained PHP code to JS

[emberdart]

People don't like PHP so Node might help with collab

Basically icebox tho

I think this would be much easier to use with https://github.com/dadi/api etc

TBH this is probably both easier and more important than thought otherwise - a lot of things can be easily replaced too. Should try doing this on a branch.

I'll make version 1 the fully JS one as most other things have already gone in that direction.
We could then potentially use things like pkg to make this easily apt installable etc.
Thoughts?
