Table justification changes forcing unnecessary work on plain tables

Since 1.1.1 (I think, DOXIA-38), the AptParser requires every row in a table to specify justification for all cells. This is onerous and for large tables makes them impossible to maintain. The old behaviour was to ignore *--- lines between rows, which I would like to re-instate if there is no change in justification.

Note that there is a related ArrayIndexOutOfBounds if you don't specify precisely the right number of columns in every row. This is really quite annoying for large tables. I think the reference for that is DOXIA-453.
