Proposal For No-Auth Cryptsy Public API

This is a raw implementation of Cryptsy's public API.  This contains all the data needed to provide the implementation for the CryptsyMarketDataService.  The only trade off is that you lose low/high and gain bid/ask on the ticker.  I wanted to check-in and see what everyones opinion was before writing up a full implementation of CryptsyMarketDataService with adapters and tests.

There is a demo added to check it out.
