fixed slua bug with Member not concating the child's instr on genAssign
added a slua object test with nested GET member access - currently fails parsing
added a slua order_of_op test with massive arithmetic expr - currently fails parsing
added a slua compiler script to emit all parser output for debugging
Hazzah! We have multi-binop expression (although no order-of-op, yet)
complex arithmetic (in the absence of oder-of-op) works!
