proof that we can wrap transaction responses easily
fixed specs
moving transaction node class entirely to core
all specs passing, running full tx support spec each time
add exclusion for embedded on transaction test
new transaction specs, removed specs too tightly bound to implementation
renamed spec file, removed requirement of wrapper to setup delegation in core
activerel find should use a query, tweaked specs for transaction support
merge master
gemfile should use core master until a new core release
Merge pull request #497 from neo4jrb/full_tx-alternate

specs and slight refactoring for better transaction support
