Onboarding Improvements

[jkmassel]

During WPYYC Contributor day, we noted a few hiccups in on boarding:

1. It seem that an Oracle JDK isn't needed anymore – Android Studio bundles one. We should get rid of that requirement in our setup steps.

2. We should note warnings that the user can expect to see, such as:

• Google Login will fail (that's ok!)
• Gradle may prompt you to update (don't do it – it'll break everything)

We should also note a couple of prerequisites:

• Supported operating systems
  • macOS, Windows(?), Linux (?)
• Required storage space to set up an Android dev environment (about 20 GB)
• You won't be able to test if your environment is a VM

It would also be great to have a list of features that can't be worked on by non-A8C devs.

Still valid. We should circle back and re-check these things in our documentation.
