- Added "Screenshot Mode" checkbox on game setup screen, which will set
units to Hold stance by default (normally, they'll be in aggress).

- Fixed a bug where repairing a building could cause you to reach
negative resources.
- Increased ranged unit LOS so they can pursue things that go out of
attack range.
- Made visibility permanent for Settlements.
- Removed a stray "s" in template_unit_cavalry_melee.xml.
