We now insert parenthesis as needed. This can cause problems in some situations, so we always prefix parenthetical expressions with "0+", which looks goofy and is unnecessary for immediate operands. But it does generate working source code. Renamed the "simple" expression mode to "common", as it's not particularly simple but is what you'd expect most assemblers to do. (OTOH, life has been full of surprises.) (issue #16)
