Embedded 3D Previewer

[benfen]

Resolves https://github.com/NREL/floorspace.js/issues/282

Port logic from https://github.com/macumber/emscripten-test to add a 3D previewer to floorspace.js. Adds an option to the Save Floorplan button to export to threeJS JSON instead; also adds a button to the top left to directly open the current floorspace in three.js.

The majority of the cpp files here are pulled from openstudio.

The PR is deployed at: https://benfen.github.io/floorspace.js/

It looks like the WASM doesn't end up in the embeddable_geometry_editor.html which the OS App uses which is good for me. I'll check that the embedded build still works in a day or two.

npm run openstudio-build is failing for me after these latest commits

macumber@Automatic-Magic-PC MINGW64 /c/repos/floorspace.js (feat/embedded-previewer)
$ npm run openstudio-build

> floorspace.js@0.7.0 openstudio-build C:\repos\floorspace.js
> node build/build.js && node build/build-embeddable.js

  Tip:
  Built files are meant to be served over an HTTP server.
  Opening index.html over file:// won't work.

I'll try to add your changes to the previewer to https://github.com/NREL/openstudio-common-measures-gem/pull/81

Had some weird issues with the build not liking a <script> tag. It's back to working again.

@bgschiller It's definitely possible - I added it to source control since I don't expect it to change frequently in comparison to the JS source code and I didn't want to add that as an additional build step/dependency.
