This adds a new module called switchboard that abuses the root React Router instance to forcibly load a chunk, letting us grab `require()` quickly rather than waiting potentially forever for another chunk to be loaded due to user action, etc.
Fix Edge not building properly. It was failing to transpile .jsx files.
Add a dev script for the babel build for Edge. It's just as bad as you'd imagine.
Stop using the env preset for babel builds and instead just use the class transform plugin.
Add logging to Module when discovering modules.
* Add automatic error reporting with Sentry.io
* Filter a bunch of bad errors from showing up on Sentry
* Add module.hasModule method.
* Fix deep_copy
* Fix disallow mouse interaction with extensions
* Add some new icons to the icon font for mod cards
* Allow Ctrl-Shift-Clicking emotes.
* Rarity sorting for experiments and unset display for unused experiments.
* Configure the project to allow the use of JSX in .jsx files.
* Add linting for JSX.
* Rewrite most existing code that uses `createElement` to use JSX syntax.
* Stop importing `createElement as e`. That's what the minifier is for. And we don't have to write it manually so much now because of JSX syntax.
