remove standard library from all sketches and require standalone_inputs to use it in standalone mode

[tzz]

@nickanderson @bheilman @zzamboni please comment

Plan:

• no more dependency on stdlib
• remove CFEngine::stdlib from DC
• test mode will specify --standalone_inputs=... to load the stdlib

Yep, I think that's a good solutions for now. We can always re-evaluate in the future. But removing standard lib from dependencies is important to make sure that sketches install and work properly when people have the stdlib present (the normal case)

The other thing we discussed about making masterfiles its own repository where the libraries live is something we could consider in the future.

For 3.6 we need to get these stdlib deps removed as we will be exposing more sketches in the enterprise ui and if they pull in the stdlib dependancy they will cause duplicate definitions.

So how will you generate a standalone runfile then? (for example for cf-sketch's "run" command).
