Release Candidate 1 for v3.0.0

Kazaam is significantly refactored to use jsonparser as the underlying JSON manipulation library, rather than go-simplejson. This results in a 2-10x improvement in time, memory usage and allocations / op for most benchmarks. See details in #35

Kazaam now takes []byte as primary transform input rather than simplejson.Json objects. String methods are still supported without change. Kazaam no longer provides full JSON validation in all scenarios, but (relatively very slow) IsJson() method is provided for convenience for users who wish to validate.
