This commit rewrite the module loader to simplify it and to improve error handling.
before this commit, you could have silent errors or "lucky" imports (import a module based on the fact that his asset will surely be load and if not, the error would be silent anyway).
e.g.: The tours cannot import modules extern to tours' bundle anymore. Or load module before your libs in assets.
