Fully convert AmiGO's JS to NPM universe

[kltm]

As more widgets convert, and as we are going to go whole hog on #104, we need to do a better job handling and building the amigo2 JS in the repo.

Things we'd like to accomplish here:

• all amigo "context" and data should be merged into /javascript/npm/amigo2 and have the application builder point there, so local installs will always have their own version
• the publicly pushed amigo2 npm should always be aligned with the public site, with separate semvar for the different branches
• all JS should be built and managed by a monolithic pipeline, no client namespace assumptions
• versioning should be much faster, automatic, and essentially increment on pushes
• remove need for "conflict" modified files to be generated during install

Okay, after much grinding, (internal) spin-out done; now need to get a handle on how to integrate this with the installer so that we no longer clobber ourselves.

TODO: need to clear unit tests for slight shifts in where things are in the DOMs now.

master amazingly passed on the first try; we're done here, any further work will likely by tweaks and #321.

Looks like it did not trigger on tomodachi.

Trigger working again and all tests are passing.
