Add support for cloud interop, window state in page saves and better builds

[johnman]

• Added a cloud interop override module so that you can easily test out OpenFin's cloud interop offering. See How To Add Cloud Interop To Your Interop Broker.
• Broke up the build process to make it easier to just build your modules. npm run build still builds everything and npm run build-client still builds all client related code but now if you change framework files you can use npm run build-framework, or if you modify our starter modules you can use npm run build-starter-modules or if you just want to build your modules (that are listed in webpack.config.js) then you can use npm run build-client-modules. This will let you have a much faster build.
• npm run launch now launches via the fins link when running on mac instead of the node adapter.
• We now capture the window state when saving a page and apply it if a page is being launched into a new window.
• Improvement: Added apply as an action on the WorkspaceChangedLifecyclePayload. Previously we had create, update, delete. update was being fired when a workspace was updated and when a workspace was applied. apply now makes it clear when a particular workspace platform override has been triggered.
