README cleanup + (c) 2014
a simpler TRINIDAD_JARS version matching - one regexp is enough!
start defaulting to "sensible" thread-safe + remove deprecated methods/configuration
move some of the Configuration (Hash helper) methods into Helpers (public api)
allow for testing with specified JRUBY_RACK_VERSION
separate rack and rails mock apps for testing (since we're going to be loading those)
update TC to 7.0.50
update trinidad.rb.jar
