Separation of the code and deploy repositories

* Removed .openshift directory
* Removed Node.JS default OpenShift cartridge files
Added initial ship.{html,css,js} Meteor files
Added Makefile to init and clean Meteor

make init:  add a .meteor directory to the current folder
make clean: remove the .meteor directory

Our .meteor folder is generated by the Makefile script and so
not included in the repository, .gitignore reflects this change.

Follow-up changes will:
    - populate the init target with changes in .meteor/ files
    - add a deploy target to prepare version ready for deployment
