Allow standalone commands before the first section

[deltaidea]

Here's a command that goes before the first section:

ai_info_map_type TYPE /* aoc */
ai_info_map_type TYPE N N N /* dlc and userpatch */

Docs: Optional command at the start of a script to tell the AI (computer player) the type of map.

The three numbers after TYPE are all 0 or 1: whether it's a nomad map (start without a TC), whether it's a michi map (teams are separated by forest), and an extra value that can be used by custom AI to detect your map.

If the map is not very similar to any of these maps, don't use ai_info_map_type.

Example: ai_info_map_type ARABIA means the map is like Arabia
In DLC/UserPatch: ai_info_map_type BLACK_FOREST 1 0 0 means it's Black Forest with nomad start.

• ARABIA
