ITX bug and patch

ITX doesn't register the variables of blocks that are inner blocks of a block created using addBlock() or addBlockfile(). if there are blocks inside blocks created by those methods, an error occurs upon calling the parse() method. attached is a patch that adds variable registration functionality for inner blocks, and adds error checking to the updateBlockvariablelist() method. thanks, dietrich
