First pass at making Distella aware of labels defined in a .sym file 

or from the user.  Before this is done, the parser needs to recognize
variable-length labels (right now, it used fixed spacing and assumes
the largest label is 8 characters).

Fixed bug in Distella; a label was being printed with an incorrect
quote symbol, which would break parsing of that line.
