Initial commit of modifications to get coinpunk to work on the vertcoin network.
Modified bitcoinjs libraries to use correct networks and address prefixes.
Changed all references to BTC to VTC and Bitcoin to Vertcoin. Renamed fork to Vertpunk.

This is NOT safe to use on a live site! You *WILL* lose your vertcoins if you try to use this in its current state!
Update README.md

Wording and formatting changes.
Complete modifications of key formats, network, and currecy references to VTC.
Add workaround cron job for publishing current VTC exchange rate locally to pricesUrl.
