Secured BuildOurOwnBabylonJSController actions
Call BuildOurOwnBabylonJS.exe once BuildOurOwnBabylonJSWinJSApp has been built

Note: whereas ourOwnBabylon.js is regenerated when F5 is pressed for BuildOurOwnBabylonJSServer, it's not when F5 is pressed for BuildOurOwnBabylonJSWinJSApp (you have to first build the app)
Typescript port in progress
Refactoring loading message management, creation a new class to handle that (in a new project).
