Update jQuery to 3.x

[shreyas-satish]

The admin interface is on 2.1.3 while the widget uses syntax (see $.get) which only works on versions >= 2.2. This inconsistency should be resolved by moving the whole app to the latest stable version of 3.x.

It might a better idea for the ticketing widget to NOT use jQuery at all. The widget mostly only depends on jQuery for making cross-domain AJAX calls, while using ractive for the bulk of state management and DOM manipulation.

Pros:

• Reduce the payload, and hence improve performance.
• Remove the jQuery dependency for a site hosting the widget, and hence make for a simpler integration process.

Cons:

• Time invested in looking for and testing a library that only does AJAX calls, or writing one ourselves. microjs lists some options.

If only AJAX is needed, then just use the SuperAgent library inline? It's just 7kb and 369 LOC.
