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.

This feels like a trainwreck but eh. Changed the way the opcodes are managed. Hopefully this is the right direction when I add support for multiple ASM files.
