Some tweaks.
Make minor city placement slightly more random.
Increase food expiration from 10 days to 25.
Correct a typo; in Interface::buiding_status(), text_benefits_label should now be populated correctly.
Allow "Q" to close an open menu.
In Player_city::start_new_city(), set all tax rates to the highest safe tax rate (that is, our race's high_tax_rate value for that Citizen_type, minus 5).
