Minor code cleanup and added an extra flag to the compiler. If a symbol is a label it will now hold a reference to the opcode and by extension the offset into the file it points to.

Massive refactoring to simplify this whole setup. The Token List will be modified in place and reused in the Parser to normalize the list and generate a symbols table. Normalizing the token list will make sure the syntax is valid and the symbols table will have the relative offsets and length of symbol values. At least this is all the plan but one step at a time.
