Proposal: Add a add command to steal-tools

[frank-dspeed]

i think it would be nice to expose a extra cli command and also programmatic to add a file to the build config aka (package.json).steal or steal.config.js

steal-tools add ./src/myNewGlobal.js --global

this should later get extras like map settings and so on
please tell me what you think about that?

What would this do exactly?
