merge new JrJackson gem v 0.1.0

While rebuilding JrJackson, I noticed that a jrjakson adapter has been added.  This version adds support for the parse options hash with symbolized_keys without needing to reparse the loaded ruby object.  Also there is a :raw key which invoke a different Java class that returns Jruby wrapped objects that quack like ruby. This is the fastest parse option but rspec equality tests comparing them to Ruby object will fail so this is not the default option.

Coverage is 100% and there are no spec failures.  HTH.

P.S. I will no doubt be having to fix issues with the new code. My JrJackson benchmarks do exercise parsing under two threads. So I trust that people using JrJackson in a concurrent environment will be OK.
