Completed initial conversion to new parser allowing spaces in operands Converted the remaining addressing modes. This required a complete rewrite of a large portion of the indexed addressing parser. Now the entire indexed parsing system is programmatic without cheating with a lookup table. This update also fixes the "force 0,r" by writing a literal 0,r which is *supposed* to work. There will likely be some pseudo ops that need tweaking for space handling, specially those that take multiple operands of some description which are not expressions. (The expression parser call eats the spaces both before and after the expression, if appropriate.)
