Better approach to external

[Saalvage]

Having to include every single external variable is aids.

Maybe we should go with something along the lines of external namespace Namespace;? This way we can still make importing deliberate.

[Saalvage]

We have to consider ambiguity in different modules though, maybe something along the lines of external namespace SCPCB/Namespace when dealing with externals from a different namespace?

[Saalvage]

On closer consideration I think we should keep the shorthand namespace parsing. It would allow for even more deliberate importing and I don't really see anything wrong with it.
