(1) Added an option to limit the number of bytes per line. This is handy for things like bitmaps, where you might want to put (say) 3 or 8 bytes per line to reflect the structure. (2) Added an application setting that determines whether the screen listing shows Merlin/ACME dense hex (20edfd) or 64tass/cc65 hex bytes ($20,$ed,$fd). Made the setting part of the assembler-driven display definitions. Updated 64tass+cc65 to use ".byte" as their dense hex pseudo-op, and to use the updated formatter code. No changes to regression test output. (Changes were requested in issue #42.) Also, added a resize gripper to the bottom-right corner of the main window. (These seem to have generally fallen out of favor, but I like having it there.)
