zdog overwrote seesaw, in which old seesaw data remains

[Overdump Detector]

Seesaw is a prototype of zdog, coming after the two vdog versions
Beware that seesaw has a whole webpage in the data, and a partial zip file
Most images from the webpage can be found on the internet archive but the web scripts have been processed to remove spammy stuff
Some code was the same or similar but i can't really read 6502 data (z80 is more understandable for me)
