Refactor evaluations (#285)

Browse Source 
* Replace evaluations with proxies and messages

* Return proxies synchronously

Otherwise events can be lost.

* Ensure events cannot be missed

* Refactor remaining fills

* Use more up-to-date version of util

For callbackify.

* Wait for dispose to come back before removing

This prevents issues with the "done" event not always being the last
event fired. For example a socket might close and then end, but only
if the caller called end.

* Remove old node-pty tests

* Fix emitting events twice on duplex streams

* Preserve environment when spawning processes

* Throw a better error if the proxy doesn't exist

* Remove rimraf dependency from ide

* Update net.Server.listening

* Use exit event instead of killed

Doesn't look like killed is even a thing.

* Add response timeout to server

* Fix trash

* Require node-pty & spdlog after they get unpackaged

This fixes an error when running in the binary.

* Fix errors in down emitter preventing reconnecting

* Fix disposing proxies when nothing listens to "error" event

* Refactor event tests to use jest.fn()

* Reject proxy call when disconnected

Otherwise it'll wait for the timeout which is a waste of time since we
already know the connection is dead.

* Use nbin for binary packaging

* Remove additional module requires

* Attempt to remove require for local bootstrap-fork

* Externalize fsevents
