Add a machinetype identifier to help us quickly identify Apple //e (bit 7) and //e enhanced (bit 6). Use it in conio functions for 80-columns code instead of relying entirely on the __APPLE2ENH__ target. Move videomode() to the apple2 target, and have it return an error if 80-columns hardware is not available - this is a lie for now, it is considered available on //e enhanced, which may not be true, and not available on //e, which may also be not true. An ulterior patch will make that check correctly. Adapt the box/line drawing characters so that one can use MouseText on the apple2 target if it is available, by defining DYN_DRAW_BOX. No change by default: MouseText is considered available on apple2enh and not available on apple2.
