Remove jQuery

[misscs]

Vision

Reduce dependencies and leverage native browser APIs.

Current State

Code base is using jQuery just to make Ajax calls (net.js). These could easily be replaced with Fetch, Async/Wait, or a single purpose node module, such as request module, that's already in the code base.

Scope

• Clarify app support requirements and goals to determine best approach
• Rewrite ajax calls in net.js to use agreed upon approach
• Remove jQuery (profit & 💃 )

As someone who's never exorcised jQuery before, i was curious and dug a little more (in case someone else wants to run with this):

jQuery Methods used (grepped $\.):

• $.get()
• $.Deferred()
• $.ajax()
• $.when()
• $.extend()
