Fix a new line preventing the jpa-demo-grocery-list to run.
Merge branch 'master' of github.com:errai/errai into develop
Finishing touches for live demo on openshift (but will move to /errai-demos/ before going live)
Removed redundant version specifications now that errai-parent is sane
updated cordova to version 2.8.1
now also copies the files to the www dir in root so we could potentially still use the cordova-cli tools in the template directory
small typo
Merge branch 'feature/update-cordova' into develop
