Create folder languages in ${OPENSHIFT_DATA_DIR} if it does not exist

For some reason the PR #58 does not create the folder "languages" in ${OPENSHIFT_DATA_DIR} before copying the languages files to it, and this just make the things not work correctly (e.g: when putting languages files on $OPENSHIFT_REPO_DIR/.openshift/languages). 

This commit fixes that.
