* Added the DelegateObject class 
* Added execBeforeMe to proteusPreinit and proteusLUPreinit to execute the adv3LibPreinit before these preinits
* Replaced references to ofKind() in the library extensions to ofKindOrUU() which includes object modifications in the ofKind() comparison.
* Change the names of Structure.t methods to be more consistent with the TADS 3 language conventions:

	structureIter			inherOrderIter
	getStructure			getInherStrucList
	getDefinedStructure		getInherDefStrucList
	getStateStructure			getInherStateStrucList
	getActionStructure			getInherActStrucList
	getDefinedActionStructure		getInherDefActStrucList
	getStructureClasses		getInherSuperclassList
