Parser now treats ':' punctuations at the beginning of a line as a 'temp label' definition. Temp labels can be referenced by ':<num>' where <num> is the index number (zero-based) of the temp label.

Parser functional and turned into a class. Tokenizer now has a tokenize() method. Both Parser and Tokenizer have been moved from MOS/6502/assembler into the compiler folder. Both Parser and Tokenizer have op code identification generalized out... which should allow Parser and Tokenizer to be used for more than one CPU type.
