Fixing serial examples
Updated Rubinius version

The RBX builds were failing unexpectedly as bundler could not be found.

https://travis-ci.org/hybridgroup/artoo-arduino/jobs/25281604

Updating to the latest version of Rubinius resolved the issue.
Merge pull request #28 from adamphillips/fix/rbx-build

Updated Rubinius version
Updating version to 1.4.3
Fixed typo

There was a typo in the require statement in artoo-arduino. This wasn't
being picked up by the tests because it wasn't being required anywhere.
Requiring caused some additional issues with other required files being
picked up so these have been updated.

In addition it was requiring the littlewire adapter which was extracted
into its own project in 2a3fa12.
