Set up continuous integration/continuous delivery

[WillieCubed]

Continuous integration (CI) is the process of continuously merging our code into a shared branch. Continuous delivery is the process of continuously

For both of these things, we use tools to make our job easier. CI allows us to verify that our code works before we merge it into our dev branch. CD allows us to automatically produce working builds of our app that we can potentially showcase for build nights.

In any case, this will be enormously beneficial when we start producing more features that might conflict with each other.

@jafrilli, could you look into CI/CD for Flutter apps? There appears to be an easy way to do this that's on the Flutter website.

This isn't really a stretch goal. It's more of a "do when we we're waiting for something else" goal.
