Revised approach to transition originating from orthogonal components (children of parallel states) to be more compliant with the SCXML specification. Fixes issues #15 and #16.
Added support for internal transitions.
Rev'd scxml-test-suite submodule, which provides tests for these features.
Re-ran make.
Fixed bug in handling of send/@delayexpr, which was causing delay expressions of the form '10ms' or '10s' to fail when passed to global setTimeout in node.js 0.6
Temporarily removed link to travis-ci

As for some reason, ci build is being run, and is failing on, unstable 'core' branch.
