High-contrast Plus42 skins

[Thomas Okken]

The question has come up how to increase the display contrast in Plus42.
Adjustable contrast is a feature I would like to implement eventually, but it's not trivial to do that with replaceable skins.

Fortunately, a user has contributed high-contrast versions of the standard skins, and I have put them up on my web site. They can be downloaded from the Plus42 skins page, or using the built-in skin loader in the Android, iOS, and Mac versions.
