APP_NAMESPACE do nothing..

@sv3tli0 - That makes sense to default it to having the Home controller namespaced. My original thinking was to default it to traditional CI3 methods where you don't have to namespace at all, but it might make more sense to default to using a namespace to get users in the habit.

I don't APP_NAMESPACE should always have a value, though, even if you don't use it, and stick to traditional patterns, in my opinion. Remember, there are two ways to use it (namespaced or traditional) and settings for one won't always make sense for the other, but that doesn't mean we want to take away the option from the other. Heck, they could mix it they wanted to, though the only time I'd recommend that is during a gradual transition from CI3.
