Build 9310396

- AI build times extended even farther for fairer gameplay
- AI places units less frequently on "normal" and "easy" difficulty
- AI places defensive tiles less often
- Units now destroy any non-defensive (and non-bridge) buildings they travel over, so you can now cut up players' territory
- Damage range for towers and ballistas have a graphic for radius
- Most UI text have outlines so they appear clearer
- All HUD values have tags that can be seen when building
