Update to latest core library versions

This release includes a ton of community commits including new translations, fixed tests, and of course version updates!

There has also been a validation sample app added to help verify setup and provide a testing environment. Instructions for running are the same as the skeleton-navigation app - npm install, jspm install, and gulp watch from the sample directory. Contributions welcome to showcase good validation techniques!

Thanks for everyone's patience, we will be sure to get the validation releases in line with the normal release cycle.
