New in this version:

- Ask/offer gold popup autofills best amount
- Adjustable minimum city distance

Changes in this version:
- Add option to increase AI artillery and bomber production
- Allow AI to grab artillery escorts from city defenders so its arty can be used in the field

New in this version:

- Enable free improvements from small wonders
- Disorder warning recomputes city happiness before running its check
- Stack bombard won't interrupt interception or auto bombard missions
- Mod loads its labels from a file, for translatability

This is a small update that fixes a problem with the city production details that I'm concerned might cause crashes.

Changes:
- Detailed city production info
- Option to limit railroad movement
- Removed unit limit
- Altered scripts so they work when run as administrator.
- Bypassed era number check (not yet a real implementation of no era limit)
- Warning message instead of crash if config file is not found
