[admin] games that do not have photographs yet -- まだ写真がないゲーム

I have created a new page for games I have listed as "Mention Only".  These are only meant as placeholders.  I hope to find proper images for these games some day.

Since I do not have photos of the game, I am moving them to a separate page.  THIS IS A HIGH PRIORITY REQUEST: If you have any photos of these games, please let me know!

写真のないマシン  --  machines with no picture

There are a few companies that have published histories of their arcade machines.  I will work to ensure that any games missing will be included in that section.  I will also compile those missing machines in the post "research materials wanted! 研究資料が欲しかった！".

Before I made the change, this is what the stats were for each page:

machines from <1970:     320
machines from 1970-1975: 374
machines from 1975-1979: 571
machines from 1980-1989: 358
machines from 1990+:     474
machines with no year:   162

After the move, here are the numbers again.

machines from <1970:     319 (-1)

machines from 1970-1975: 354 (-20)

machines from 1975-1979: 558 (-13)

machines from 1980-1989: 329 (-29)

machines from 1990+:     474

machines with no year:   162

machines only mentioned: 63
