Suggestion: Make sure money warnings also apply if costs are too low

• As per title
• After doing this, maybe set the default configs to start at 0?
  • That way new installs would immediately guide the admin in the right direction.

• Checked it
• The warnings do apply if costs are too low

• I don't think I will do the bit about changing the amounts, I think the warnings are sufficient. But I will adjust the user guide to say not to bother adjusting the amounts before starting.
