coldet:
	get rid of TYPE_FOOTPRINT, it was an alias for TYPE_SPHERE in the continuous
	case which is now default and the original intent (a shape defined by the CSG
	intersection of sphere and footprint) would have been tricky to get right

	instead support a {Unit,Feature}Def key "useFootPrintCollisionVolume" which
	makes a collision volume a box with dimensions equal to the object's footprint
	(this overrides any custom scaling and/or offsets)

	add missing default c'tor for SolidObjectDecalDef

	general code cleanup
