add default app.js

suggest to add an empty js/app.js and already integrated in all the resources component of the existing layouts.
right now, I have to override ALL the layouts just to add my custom app.js. I think it will be helppful for anyone else.

I think so too. The caveat to this is that every project is different and it wouldn't make sense to include a file that isn't following their naming conventions.

I think what we should do instead is include a partial specifically for assets so editing files can be easier.

I actually did just that in v5.0.3. I moved all the assets to a new partial called assets.htm so you don't have to touch the layout files. It makes for adding assets easier in my opinion.
