Option to create a new project

Received via internal bug feedback tool:

This is my second run trying out the Run Deploy and I figured it out so this screenshot isn't relevant but I think it'd be helpful if:

1. After you select a project and get an error message, you can select another one instead of just being stuck trying to fix payment options for that project
2. Be clearer about how to add a payment method and how much that payment will be. Just link to it more directly

tl;dr consider adding "New Project" option to the project selector, and handle billing errors in a more friendly way.

New Project option would certainly help.
