Progress toward 64tass support Most tests pass, but 2007-labels-and-symbols fails because the expressions recognized by 64tass don't match up with either of the other assemblers. This is currently using a workaround for the local label syntax. 64tass uses '_' as the prefix, which is unfortunate since SourceGen explicitly allowed underscores in labels. (So does 64tass for that matter, but it treats labels specially when the '_' comes first.) We will need to rename any non-local user labels that start with '_'. (issue #16)

Get 64tass expressions working 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)
