Added a SymbolTable object (untested at the moment) and redefined the Symbol object. I think when a Symbol is made only the size of it should matter to the code that will assemble the final binary.

Changed the TokenClass from opcode to nomic, a less smoothbrain name IMO and also frees up Opcode for a better use later on.
