Vertical button images for vertical games

Vertical games now have a 240x320px vertical button image, which looks much better in PinHP for vertical games on a rotated screen.

Button images update with new logo sources

v1.5

Button images updated with new logos

No one left behind

Oops, the example image for Shadow Force that I was testing with was missing from the v1.4 release - fixed that.

Extra 202 logos

Filled in 202 missing logos using Arcade Italia - e.g. http://adb.arcadeitalia.net/media/mame.current/decals/shadfrce.png

South aligned logo images

All logo images now aligned south for better layout in PinHP frontend.

Fewer logos, better quality

Now only includes logo images for roms that exist in MAME 0.106

An extra source was included from https://hyperspin-fe.com/files/file/8146-default-mame-game-wheel-pack - which has slightly higher quality images than the earlier assets which were primarily from https://emumovies.com/files/file/1969-mame-game-logo-pack/.

There are now 4,936 logos in total.

Better buttons

Regenerated all button images to use latest/improved logo set

Initial release for PinHP

v1.0
