Incorporate changes for chatbot

* #175 from @mojavelinux
* #176 from @ericgimproving

I had to make the following changes:

* use the origin property instead of URL, to match referer
* comment out the send-intent line (no such element exists?)
* currently we're still using the bundled version: I couldn't get the `require` of the github installed package to work.
* (minor linting change for another sandbox experiment on docsearch... please ignore)
