* Update Node to 10.15.1

* Remove string replace that was used for oclif

* Update nbin

* Package node-pty and spdlog with nbin

* Label stderr/stdout from shared process

* Remove fork override

* Prevent "already disposed" errors when trying to kill disposed proxies

* Include spdlog dependencies

* Shim /node_modules

* Add node_modules to Docker ignore

It keeps using my already-built .node files which results in a
mismatching GLIBC version error.

* Update nbin
