[deathaxe]

This PR incooperates some changes to get up and running more quickly.

1. Postgre failed to start as it couldn't create /var/run/postgresql, so added it to the scripts.
2. Improve overall database initialization in dev-servers.sh for easiear start.
3. Start dev-servers.sh via dev.sh so all development related servers start with a single command.
   Found it confusing to fail due to not running databse/redis server.
4. Add a hint about new basic auth secrets.
