Use the development settings by default instead of local

We don't really need people to define a local settings file, let's just create
a config that is usable for everybody.
plain make now does everything and starts a server

This should make it easier for new people to join the team.

This keeps current setups working, while still allowing youarehero to be run
without any configuration.

We don't just catch ImportError because that could mask some valid issues.
