World Builder: Scripts: Enhancement: Add a script condition that checks for Map Size

[toirehantaa]

Adding a condition that checks for Map Size will make it easier for AI-scripters to determine neighbouring perimeters / player bases

Agreed + adding inner outer , combatzone triggers and more on every map is cumbersome(it should be optional not required)-- sage 2 games like redalert 3 dont even use them anymore -> quite shocking tbh
