Removed implementation file; this is only ever going to be a template.

Actually, this is probably more correct: increment and then compare, but increment the refresh address once more after the final character, to avoid repeating it.

Switched to post-tests increment. Seems to give proper screen width, but also eliminates that 'compare to +1' step that felt unlikely.

Made a quick attempt at properly updating the refresh address.

I was under-counting row lines. Adjusted comparison. The emulator now produces a solid white square of approximately correct proportions. I'm sure that filling in pixels will reveal the next set of bugs.

Fixed display enable reset when there's no adjustment area. A practical lesson in failure to factor.

I'm sure it's not going to be this easy, but this is a genuine attempt at full horizontal and vertical timing.

Corrected CRTC timing, gave it someone to talk to and a means with which to talk.

Created a 6845 class and started pushing data at it and clocking it. It doesn't currently have the concept of a bus but will do, hence the in-header implementation.
