Added ground work for tester tool
tester tool works but needs to fill out list of acceptable datablocks and spawnclasses
navpaths now share 1 navmeshquery
AIControllerData now has a vector of area costs for different polyareas
General cleanup
SceneObject now defaults to a category of "misc"
getCategoryOfClass now checks parent classes for what categories they hold so that variants can inherit
categories are in one of a few rough groups and subgroups depending on actual mapper needs/usages
