Cypress plugin

I need to publish this to a proper module somewhere, but it was hell to get working right so I want to bookmark it somewhere public for anyone else searching: https://github.com/JarvusInnovations/emergence-skeleton/blob/develop/cypress/support/commands.js#L110

For those testing an ExtJS application with Cypress, this gives you a cy.extGet() command that works like the built-in cy.get() but with component queries, and supports all the Cypress magic (chaining, retrying until forward assertions pass)
