Basic loading into frosting

I had what we need for the system to be used in the frosting system.

I'll let you check if you want to integrate it that way instead of doing proxy class and everything...

Like you can see I just add the frosting.json file and a @Inject annotation in the javascript renderer. It should not have any impact on other thing.

For your information on the frosting end what we need to do is one of the frosting.json file put in the imports section: "mpoiriert/php-debugbar" (will change when the merge is done). The system will detect that there is a frosting.json file in the vendor directory and load it.
