Updated the opcode listing and 'fixed' the code to at least compile, but obviously I'll need to rework how the new copy instructions are to be parsed. Fixed some errors in the documentation where I skipped some hex numbers and added a copy immediate op.

Fixed up the RemoveCurrentToken function which was causing all sorts of bugs, and added the ability to delcare a data byte, '.db', to have a variable's address as a value. This will be needed for building up an interrupt table at least with the version I have in mind.

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.
