Added lightbeam-feedback@mozilla.org as contact information to CONTRIBUTING.md.
Also updated all instances of our Electrolyfish repo URL in the docs to Mozilla.
Also snuck in an eslint rule for spaces between operators so we don't see `var x=4`.
Still using a `this._websites` local copy. Literally just swapped out localStorage for IndexedDB. I had originally tried getting rid of `this._websites`, but this made almost every method async, and there were numerous update errors in `store.addFirstPartyLink`.
@todo:
* Consider using canvas instead of svg elements
* Consider using a callback in storage to update visualization
* Currently the storage data is reformatted with a function transformData; consider alternatives.
