Add a test projects page
Create layout specifically for error pages. This is needed mostly so that we don't include analytics code in error pages, which using simple-layout was doing.
Prepend '/' to urls gotten from asset_url() to make them absolute. This fixes /projects/* documentation not displaying correctly.
Rename endpoints for api functions in minecraft_api to be more explicit.
Add workaround for frozen-flask generating static pages for dynamic api pages like /oauth/.
